Megalithic

Megalithic

A megalith is a large stone which has been used to construct a structure or monument either alone or with other stones. Megalithic means made of such stones, but uses a interlocking system without the use of mortar or cement. The word megalith comes from the Ancient Greek megas meaning large, and lithos meaning stone.

Distribution of megaliths

The term can be used to describe buildings erected by people from many parts of the world living in many different periods. In the early 20th century, some scholars believed that all megaliths belonged to one global "Megalithic culture" (Hyperdiffusionism, e. g. by Grafton Elliot Smith and William James Perry), but this has long been disproved by modern dating methods.

Nabta Playa

William James Perry Nabta Playa was once a large lake in the Nubian Desert, located 500 miles south of modern day Cairo [http://www.archaeology.org/online/news/nubia.html]. By the 5th millennium BC the peoples in Nabta Playa had fashioned the world's earliest known astronomical device, 1000 years older than but comparable to Stonehenge [http://www.comp-archaeology.org/WendorfSAA98.html]. Research shows it to be a prehistoric calendar that accurately marks the summer solstice [http://www.comp-archaeology.org/WendorfSAA98.html]. Findings indicate that the region was occupied only seasonally, likely only in the summer when the local lake filled with water for grazing cattle [http://hej3.as.utexas.edu/~www/wheel/africa/nabta_01.htm], [http://www.comp-archaeology.org/WendorfSAA98.html].

Western European megaliths

In Western Europe and the Mediterranean, megaliths are generally constructions erected during the Neolithic or late stone age and Chalcolithic or Copper Age (4500 - 1500 B.C.E). Perhaps the most famous megalithic structure is Stonehenge in England, although many others are known throughout the world. The French Comte de Caylus was the first to describe the Monuments of Carnac. Legrand d'Aussy introduced the terms menhir and dolmen, both taken from the Breton language, into antiquarian terminology. He interpreted megaliths as gallic tombs. In Britain, the antiquarians Aubrey and Stukeley conducted early research into megaliths. In the year XIII (1805) Jacques Cambry published a book called Monuments celtiques, ou recherches sur le culte des Pierres, précédées d'une notice sur les Celtes et sur les Druides, et suivies d'Etymologie celtiques, where he proposed a Celtic stone cult. This completely unfounded connection between druids and megaliths has haunted the public imagination since. druids druids

Types of megalithic structures

Different megalithic structures include:
- Dolmen (or cromlech in Welsh): This is a free standing chamber consisting of standing stones covered by a capstone as a lid. They were used for burial and were covered by mounds.
- Menhir: This is single standing stone.
- Orthostat: This is an upright slab forming part of a larger structure.
- Stone circle
- Stone row
- Stone ship
- Taula: This is a straight standing stone, topped with another forming a 'T' shape.
- Trilithon: Two parallel upright stones with a horizontal stone (called a lintel) placed on top, e.g. Stonehenge.

Megalithic graves

Main article: Megalithic tomb Many megalithic monuments were burial mounds which were often re-used by different generations. The chambered cairn is a common type of collective tomb. Some of these are passage graves generally built of drystone walling and/or megaliths often with a round burial chamber in a round mound with a straight passage leading out. Gallery graves have a long megalithic chamber with parallel sides often in a long mound with an entrance at one end.

Astronomical use

Many megaliths were thought to have a purpose in determining important astronomical events such as the solstice and equinox dates (see archaeoastronomy). Cup marks on megaliths have been thought by some to represent stars and thus to show the stellar orientation of megalithic sites.

Modern megaliths

There are even some modern megalithic structures. The Coral Castle is an unusual stone structure created in the 1920s in Homestead, Florida by Edward Leedskalnin. Edward Leedskalnin]]

Rock (geology)

, plutonic, metamorphic rock types of North America. ]] Rock is a naturally occurring aggregate of minerals and/or mineraloids. Rocks are classified by mineral and chemical composition; the texture of the constituent particles; and also by the processes that formed them. These indicators separate rocks into igneous, sedimentary, and metamorphic. Igneous rocks are formed from molten magma, and are divided into two main categories: Plutonic rock and Volcanic rock. Plutonic rocks result when the magma cools and crystallises slowly within the Earth's crust, while Volcanic rocks result from the magma reaching the surface either as lava or fragmental ejecta. Sedimentary rocks are formed by deposition of either detrital or organic matter, or chemical precipitates (evaporites), followed by compaction of the particulate matter and cementation. The latter can occur at or near the earth's surface, especially in the case of carbonate-rich sediments. Metamorphic rocks are formed by subjecting any rock type (including previously-formed metamorphic rock) to different temperature and pressure conditions than those in which the original rock was formed. These temperatures and pressures are always higher than those at the earth's surface, and must be sufficiently high so as to change the original minerals into other mineral types or else into other forms of the same minerals (e.g. by recrystallisation). The transformation of one rock type to another is described by the geological model called the rock cycle. The Earth's crust (including the lithosphere) and mantle are formed of rock.

Greek language

Greek (Greek Ελληνικά, IPA – "Hellenic") is an Indo-European language with a documented history of 3,500 years. Today, it is spoken by 15 million people in Greece, Cyprus, the former Yugoslavia, particularly The Former Yugoslav Republic of Macedonia, Bulgaria, Albania and Turkey. There are also many Greek emigrant communities around the world, such as those in Melbourne, Australia which is the third-largest Greek-populated city in the world, after Athens and Thessaloniki. Greek has been written in the Greek alphabet, the first true alphabet, since the 9th century B.C. and before that, in Linear B and the Cypriot syllabaries. Greek literature has a long and rich tradition.

History

This article does not cover the reconstructed history of Greek prior to the use of writing. For more information, see main article on Proto-Greek language. Greek has been spoken in the Balkan Peninsula since the 2nd millennium BC. The earliest evidence of this is found in the Linear B tablets dating from 1500 BC. The later Greek alphabet (q.v.) is unrelated to Linear B, and was derived from the Phoenician alphabet (abjad); with minor modifications, it is still used today. Greek is conventionally divided into the following periods:
- Mycenean Greek: the language of the Mycenean civilisation. It is recorded in the Linear B script on tablets dating from the 16th century BC onwards.
- Classical Greek (also known as Ancient Greek): In its various dialects was the language of the Archaic and Classical periods of Greek civilisation. It was widely known throughout the Roman empire. Classical Greek fell into disuse in western Europe in the Middle Ages, but remained known in the Byzantine world, and was reintroduced to the rest of Europe with the Fall of Constantinople and Greek migration to Italy.
- Hellenistic Greek (also known as Koine Greek): The fusion of various ancient Greek dialects with Attic (the dialect of Athens) resulted in the creation of the first common Greek dialect, which gradually turned into one of the world's first international languages. Koine Greek can be initially traced within the armies and conquered territories of Alexander the Great, but after the Hellenistic colonisation of the known world, it was spoken from Egypt to the fringes of India. After the Roman conquest of Greece, an unofficial diglossy of Greek and Latin was established in the city of Rome and Koine Greek became a first or second language in the Roman Empire. Through Koine Greek it is also traced the origin of Christianity, as the Apostles used it to preach in Greece and the Greek-speaking world. It is also known as the Alexandrian dialect, Post-Classical Greek or even New Testament Greek (after its most famous work of literature).
- Medieval Greek: The continuation of Hellenistic Greek during medieval Greek history as the official and vernacular (if not the literary nor the ecclesiastic) language of the Byzantine Empire, and continued to be used until, and after the fall of that Empire in the 15th century. Also known as Byzantine Greek.
- Modern Greek: Stemming independently from Koine Greek, Modern Greek usages can be traced in the late Byzantine period (as early as 11th century). Two main forms of the language have been in use since the end of the medieval Greek period: Dhimotikí (Δημοτική), the Demotic (vernacular) language, and Katharévousa (Καθαρεύουσα), an imitation of classical Greek, which was used for literary, juridic, and scientific purposes during the 19th and early 20th centuries. Demotic Greek is now the official language of the modern Greek state, and the most widely spoken by Greeks today. It has been claimed that an "educated" speaker of the modern language can understand an ancient text, but this is surely as much a function of education as of the similarity of the languages. Still, Koinē , the version of Greek used to write the New Testament and the Septuagint, is relatively easy to understand for modern speakers. Greek words have been widely borrowed into the European languages: astronomy, democracy, philosophy, thespian, etc. Moreover, Greek words and word elements continue to be productive as a basis for coinages: anthropology, photography, isomer, biomechanics etc. and form, with Latin words, the foundation of international scientific and technical vocabulary. See English words of Greek origin, and List of Greek words with English derivatives.

Classification

Greek is an independent branch of the Indo-European language family. The ancient languages which were probably most closely related to it, Ancient Macedonian language (which may be regarded as a dialect of Greek) and Phrygian, are not well enough documented to permit detailed comparison. Among living languages, Armenian seems to be the most closely related to it.

Geographic distribution

Modern Greek is spoken by about 15 million people mainly in Greece and Cyprus. There are also Greek-speaking populations in Georgia, Ukraine, Egypt, Turkey, Albania, Former Yugoslav Republic of Macedonia and Southern Italy. The language is spoken also in many other countries where Greeks have settled, including Armenia, Australia, Austria, Belgium, Bulgaria, Canada, Denmark, France, Germany, Netherlands, Sweden, United Kingdom, and the United States.

Official status

Greek is the official language of Greece where it is spoken by about 99.5% of the population. It is also, alongside Turkish, the official language of Cyprus. Due to the membership of Greece and Cyprus, Greek is one of the 20 official languages of the European Union.

Nabta Playa

Nabta Playa was once a large basin in the Nubian Desert, located approximately 500 miles south of modern day Cairo [http://www.archaeology.org/online/news/nubia.html] or about 100 kilometers west of Abu Simbel of southern Egypt [http://www.comp-archaeology.org/WendorfSAA98.html], 22° 32' north, 30° 42' east [http://sunearthday.nasa.gov/2005/locations/egypt_stone.htm]. Today the region is characterized by numerous archaeological sites [http://www.comp-archaeology.org/WendorfSAA98.html].

Early History

Beginning around the 10th millennium BC, this region of the Nubian Desert began to receive more rainfall, filling a lake [http://www.comp-archaeology.org/WendorfSAA98.html]. Early peoples may have been attracted to the region as a source of water for grazing cattle. Archaeological findings indicate occupation in the region dating to somewhere between the 10th and 8th millennia BC [http://www.comp-archaeology.org/WendorfSAA98.html]. These peoples were herding domesticated cattle and using ceramics [http://www.comp-archaeology.org/WendorfSAA98.html] adorned by complicated painted patterns created perhaps by using combs [http://www.comp-archaeology.org/WendorfSAA98.html]. By the 7th millennium BC, exceedingly large and organized settlements may be found in the region, relying also on deep wells for sources of water [http://www.comp-archaeology.org/WendorfSAA98.html]. Huts are found constructed in straight rows [http://www.comp-archaeology.org/WendorfSAA98.html]. Sustenance included fruit, legumes, millets, sorghum and tubers [http://www.comp-archaeology.org/WendorfSAA98.html]. Also in the 7th millennium BC, but a little later than above, imported goats and sheep, apparently from Southwest Asia [http://www.comp-archaeology.org/WendorfSAA98.html], appear. Many large hearths also appear [http://www.comp-archaeology.org/WendorfSAA98.html].

High level of organization

Archaeological discoveries reveal that these prehistoric peoples led livelihoods seemingly at a higher level of organization than their contemporaries who lived closer to the Nile Valley [http://www.comp-archaeology.org/WendorfSAA98.html]:
- above-ground & below-ground stone construction,
- villages designed in pre-planned arrangements, and
- deep wells that held water year-round. Findings also indicate that the region was occupied only seasonally, likely only in the summer when the local lake filled with water for grazing cattle (see [http://hej3.as.utexas.edu/~www/wheel/africa/nabta_01.htm], [http://www.comp-archaeology.org/WendorfSAA98.html]). Analysis of human remains suggest migration from sub-Saharan Africa [http://hej3.as.utexas.edu/~www/wheel/africa/nabta_01.htm].

Religious ties to ancient Egypt

By the 6th millennium BC, evidence of a prehistoric religion or cult appears, with a number of sacrificed cattle buried in stone-roofed chambers lined with clay [http://www.comp-archaeology.org/WendorfSAA98.html]. It has been suggested that the associated cattle cult indicated in Nabta Playa marks an early evolution of Ancient Egypt's Hathor cult. For example, Hathor was worshipped as a nighttime protector in desert regions (see Serabit el-Khadim). To directly quote professors Wendorf and Schild [http://www.comp-archaeology.org/WendorfSAA98.html] (1998): :... there are many aspects of political and ceremonial life in the Predynastic and Old Kingdom that reflects a strong impact from Saharan cattle pastoralists... which suggests that the Old Kingdom belief system was imposed from the outside, perhaps ... a conquest by pastoralists (Coon 1958:295-323; Khazanov 1994). Nevertheless, though the religious practices of the region involving cattle suggest ties to Ancient Egypt [http://www.comp-archaeology.org/WendorfSAA98.html], Egyptologist Mark Lehner [http://www.archaeology.org/online/news/nubia.html] cautions: :It makes sense, but not in a facile, direct way. You can't go straight from these megaliths to the pyramid of Djoser. Djoser Other subterranean complexes are also found in Nabta Playa, one of which included evidence of perhaps an early Egyptian attempt at sculpture [http://www.comp-archaeology.org/WendorfSAA98.html].

World's earliest known archeoastronomy

By the 5th millennium BC these peoples had fashioned the world's earliest known archeoastronomical device, about 1000 years older than but comparable to Stonehenge [http://www.comp-archaeology.org/WendorfSAA98.html] (see sketch at right). Research suggests that it may have been a prehistoric calendar which accurately marks the summer solstice [http://sunearthday.nasa.gov/2005/locations/egypt_stone.htm].

Nubia

:This article is about the region in Africa, for other uses see Nubia (disambiguation) Today Nubia is the region in the south of Egypt, along the Nile and in northern Sudan, but in ancient times it was an independent kingdom. Sudan ]] Its people spoke at least two varieties of the Nubian language group, a Nilo-Saharan subfamily which includes Nobiin, Kenuzi-Dongola, Midob and several related varieties in the northern part of the Nuba Mountains in South Kordofan. A variety (Birgid) was spoken (at least until 1970) north of Nyala in Darfur but is now extinct. Old Nubian was used in mostly religious texts dating from the 8th and 9th centuries AD. It is considered ancestral to modern day Nobiin.

History

Pre-history

The earliest cultures of Nubia left no writings and are unreported in the annals of other nations. The first noticeable cultures in Nubia include first the Badarian culture, then the Amratian and finally the Gerzean. From the Gerzean the first native culture developed known as the A-Group, which began roughly at the same time as the First dynasty of Egypt around 3100 BC. It consisted of semi-nomadic groups who subsided by herding sheep, goats, and some cattle. It is known from its distinctive burial rituals and pottery. Prehistoric tools discovered in Nubia date to circa 65,000 BC, found along the Nile Valley [http://smu.edu/newsinfo/releases/01033.html]. This culture began to decline in the early 28th century BC. The succeeding culture is known as B-Group. Previously the B-Group people were thought to have invaded from elsewhere. Today most historians believe that B-Group was merely A-Group but far poorer. The causes of this is uncertain, but it was perhaps caused by Egyptian invasions and pillaging that began at this time. As trade between Egypt and Nubia increased so did wealth and stability. By the Egyptian 6th dynasty Nubia was divided into a series of small kingdoms. There is debate over whether these C-Group peoples, who flourished from c. 2240 BC to c. 2150 BC, were another internal evolution or invaders. There are definite similarities between the pottery of A-Group and C-Group, so it may be a return of the ousted Group-As, or an internal revival of lost arts. At this time the Sahara Desert was becoming too arid to support human beings and it is possible that there was a sudden influx of Saharan nomads. C-Group pottery is characterized by all over incised geometric lines with white infill and impressed imitations of basketry. A contemporaneous but distinct culture from the C-Group was the Pan Grave culture, so called because of their shallow graves. The Pan Graves are associated with the East bank of the Nile, but the Pan Graves and C-Group defintiely interacted. Their pottery is characterized by incised lines of a more limited character than the C-Group, generally having interspersed undecorated spaces within the geometric scheme. From the C-Group culture the first kingdom to unify much of the region arose, the Kingdom of Kerma, named for its presumed capital at Kerma. When Egyptian power revived under the New Kingdom they began to expand southwards. By the end of the reign of Thutmose I in 1520 BC all of northern Nubia had been annexed.

Kush

Thutmose I When the Egyptians pulled out, they left a lasting legacy that was merged with indigenous customs forming the kingdom of Kush. Kush adopted many Egyptian practices such as their religion and the practice of building pyramids. The kingdom of Kush survived longer than that of Egypt, even invading and controlling Egypt itself for a period (the Kushite dynasty) in the 8th century BC. Kush was never annexed by the Romans. The Kushites did trade with the Romans, and were also a source of mercenaries. During this time, the different parts of the region divided into smaller groups with individual leaders, or generals, each commanding small armies of mercenaries. They fought for control of what is now Nubia and its surrounding territories, leaving the entire region weak and vulnerable to attack. At some point, Kush was conquered by the Noba people, from which the name Nubia may derive (another possibility is that it comes from Nub, the Egyptian word for gold). From then on, the Romans referred to the area as the Nobatae. Indeed, recent studies in population genetics suggest that there was a south-north gene flow through the Nile Valley. Similarly, linguistic evidence suggests that the Nubians from the Nile Valley originally came from the south or southwest. Historical comparative research into the Nubian language group has indicated that the Nile-Nubian languages must have split off from the Nubian languages still spoken in the Nuba Mountains in Kordofan, Sudan, at least 2500 years ago.

Christian Nubia

Around AD 350 the area was invaded by the Ethiopian kingdom of Axum and the kingdom collapsed. Eventually three smaller kingdoms replaced it: northernmost was Nobatia between the first and second cataract of the Nile River, with its capital at Pachoras (modern day Faras); in the middle was Makuria, with its capital at Old Dongola; and southernmost was Alodia, with its capital at Soba (near Khartoum). King Silko of Nobatia crushed the Blemmyes, and recorded his victory in a Greek inscription carved in the wall of the temple of Talmis (modern Kalabsha) around AD 500. While bishop Athanasius of Alexandria consecrated one Marcus as bishop of Philae before his death in 373, showing that Christianity had penetrated the region by the fourth century, John of Ephesus records that a Monophysite priest named Julian converted the king and his nobles of Nobatia around 545. John of Ephesus also writes that the kingdom of Alodia was converted around 569. However, John of Bisclorum records that the kingdom of Makuria was converted to Roman Catholicism the same year, suggesting that John of Ephesus might be mistaken. Further doubt is cast on John's testimony by an entry in the chronicle of the Greek Orthodox Patriarch of Alexandria Eutychius, which states that in 719 the church of Nubia transferred its allegiance from the Greek Orthodox to the Coptic Church. By the 7th century Makuria expanded becoming the dominant power in the region. It was strong enough to halt the southern expansion of Islam after the Arabs had taken Egypt. After several failed invasions the new rulers agreed to a treaty with Dogomba allowing for peaceful coexistence and trade. This treaty held for six hundred years. Over time the influx of Arab traders introduced Islam to Nubia and it gradually supplanted Christianity. While there are records of a bishop at Qasr Ibrim in 1372, his see had come to include that located at Faras. It is also clear that the "Royal" church at Dongola had been converted to a mosque around 1350.

Modern Nubia

In the 14th century the Dongolan government collapsed and the region became divided and dominated by Egypt. The next centuries would see several invasions of the region, as well as the establishment of a number of smaller kingdoms. Northern Nubia was brought under Egyptian control while the south came under the control of the Kingdom of Sennar in the sixteenth century. The entire region would come under Egyptian control during the rule of Mehemet Ali in the early nineteenth century, and later became a joint Anglo-Egyptian condominium. With the end of colonialism Nubia was divided between Egypt and Sudan. Many Egyptian Nubians were forcibly resettled to make room for Lake Nasser after the construction of the dams at Aswan. Nubian villages can now be found north of Aswan on the west bank of the Nile and on Elephantine Island, and many Nubians live in large cities such as Cairo.

Cairo

have become a symbol of Cairo internationally]] Cairo (Arabic: القاهرة; transliterated: al-Qāhirah) is the capital city of Egypt (and previously the United Arab Republic) and has a metropolitan area population of approximately 15.2 million people. Cairo is the sixteenth most populous metropolitan area in the world. Cairo is located at 30°2' North, 31°13' East (30.03333, 31.21667). [http://earth-info.nga.mil/gns/html/cntry_files.html] While al-Qāhirah is the official name of the city, in local speech it is typically called simply by the name of the country, Mişr (Arabic, مصر) pronounced Maşr in the local dialect. The name Al-Qahirah literally means "The Subduer," though it is often translated as "The Victorious." The origin of the name is said to come from the appearance of the planet Mars during the foundation of the city. The planet Mars, associated with destruction was called "Al Najm Al Qahir" in Arabic, from which the name of the city was derived. However the legacy of the name evolved into the title "Qahirat Al Adaa" meaning "subduer of the enemies". This title was given to the city as many armies were destroyed in attempts to invade Cairo or defeated elsewhere by troops sent from Cairo. (Mongols, Crusaders & Ottomans are examples.) Mongols

Geography

Mongols Mongols Cairo is located on the banks and islands of the Nile River in the north of Egypt, immediately south of the point where the river leaves its desert-bound valley and breaks into three branches into the low-lying Nile Delta region. The oldest part of the city is somewhat east of the river. There, the city gradually spreads west, engulfing the agricultural lands next to the Nile. These western areas, built on the model of Paris by Ismail the Magnificent in the mid-19th century, are marked by wide boulevards, public gardens, and open spaces. The older eastern section of the city is very different: having grown up haphazardly over the centuries it is filled with small lanes and crowded tenaments. While western Cairo is dominated by the government buildings and modern architecture, the eastern half is filled with hundreds of ancient mosques that act as landmarks. Extensive water systems have also allowed the city to expand east into the desert. Bridges link the Nile islands of Gezira and Roda, where many government buildings are located and government officials live. Bridges also cross the Nile attaching the city to the suburbs of Giza and Imbabah (part of the Cairo conurbation). West of Giza, in the desert, is part of the ancient necropolis of Memphis on the Giza plateau, with its three large pyramids, including the Great Pyramid of Giza (last surviving of the Seven Ancient Wonders of the World). Approximately 11 miles (18 km) to the south of modern Cairo is the site of the ancient Egyptian city of Memphis and adjoining necropolis of Saqqara. These cities were Cairo's ancient predecessors, when Cairo was still in this approximate geographical location.

History

Founding and early history

Saqqara Saqqara Old City. Cairo has the largest concentration of mediæval structures in the world.]] The current location of Cairo was too far from the ancient course of the Nile to support a city. Just to the south of the modern city's location are the ruins of Memphis, which was the capital of Ancient Egypt and was founded in around 3100 BC by Menes of Tanis after he had united the two kingdoms of Upper and Lower Egypt, although the capital later moved to Heliopolis, further south to Thebes, and, under the Ptolemaic dynasty, Alexandria. The first settlement on the location of modern Cairo was a Roman fort, known as Babylon Fort, built about AD 150, built near the settlement known as Babylon-in-Egypt, which lay close to an ancient Egyptian canal from the Nile to the Red Sea. A small town mostly of Coptic Christians slowly grew around the fort. Arab invaders, lead by Amr Ibn-el-As, took the fort town in 642 and also established their army in the location, rebuilding its defenses. The Arab tented camp outside the fortress, known as Al-Fustat, slowly became the permanent base of the Arab forces in Egypt under the Umayyads and Abbasids, and contains the first mosque in Africa. Slowly, the settlement grew into a small city. The North African Shiite Fatimid Dynasty conquered Egypt in 972 and built a new capital, Al-Mansureya, north of the old settlement. Their leader, Al-Muez Ledin-Ellah, renamed the city Al-Qahirah after the planet Mars which was rising on the day the city was founded. The Al-Azhar mosque was founded the same year, and along with its accompanying university it made Cairo a centre of learning and philosophy. The school remains a major center for Islamic study today. The Seljuks captured Cairo in the mid 1100s, and Saladin and his successors expanded the city further, including the construction of its massive citadel. The sack of Baghdad in 1258 heightened the importance of the city and it became the leading intellectual and artistic centre in the Middle East, and perhaps the world, for the next 250 years. But power was shifting from the Arab world north to the Turks and Europeans. The city was taken by the Ottoman Empire under Selim I in 1517, but the ruling Mameluks quickly returned to power as nominal vassals to the Ottoman Sultan.

Era of westernization

Mameluks Mameluks Mameluks Napoleon conquered Egypt in 1798, and Cairo was quickly surrendered to him by its Mameluk rulers. Napoleon left Egypt after his fleet was destroyed at the Battle of Aboukir Bay in August 1798, leaving General Kléber in charge. Kléber was assassinated in 1800 and the three-year French occupation had little lasting effect. The first hints of westernization began under the successors to Mehemet Ali with the introduction of a railway connection to Alexandria in 1851. Significant change, however, did not occur until the reign of Isma'il Pasha when, in 1863, construction of the Suez Canal brought significant numbers of westerners to Egypt. A network of gas lighting was installed by a French company and the railway lines were greatly expanded. In 1867, Isma'il visited Paris to attend the Universal Exposition of 1867. There he saw the newly redesigned city of Haussmann and, funded by a booming cotton trade, decided to rebuild Cairo on the model of a European capital. He hoped to have this done by 1869 when representatives from around the world came to Egypt for the opening of the Suez Canal. Rather than rebuild the old city, Isma'il elected to add a new quarter to the western section along the bank of the Nile. The project was carried out by Ali Pasha Mubarak and designed by the French urban planner Pierre Grand. A new area of luxurious villas and apartments was constructed and new government ministries were erected. Grand boulevards were opened through the old town and tram lines soon followed. The era of colonization in 1882 saw the rebuilding of Cairo continuing. A modern sewer system was installed and new suburbs such as Heliopolis were constructed in the desert. Cairo's population exploded, increasing from 374,000 in 1882 to 1,312,000 by 1937. The city was dominated by westerners, however, and city planners tended to emphasize Christian cathedrals over mosques.

Modern Cairo

Cairo remained the central city of Egypt throughout the period of British rule and afterwards. The 20th century saw massive growth in the size of the city as peasants left the farmlands in pursuit of work in the factories and commerce of the metropolis. The city was especially burdened by refugees from the various wars with Israel: much of the population of the Sinai peninsula and the cities along the Suez Canal left for Cairo between 1967 and 1978. Today Cairo is Africa's most populous city and the Arab world's cultural centre. Since the 19th century Cairo has also become a center for tourism as people from around the world have come to see the monuments and artifacts of Ancient Egypt, especially the Pyramids. Laws against the export of these treasures has meant that the Egyptian Museum in Cairo is the only place in the world that many items can be seen.

Astronomy

:This article is about the science branch. For information about the magazine, see Astronomy (magazine). Astronomy (magazine) as they circled the Moon in 1969. Located near the center of the far side of Earth's Moon, its diameter is about 58 miles (93 km).]] Astronomy (Greek: αστρονομία = άστρον + νόμος, astronomia = astron + nomos, literally, "law of the stars") is the science of celestial objects and phenomena that originate outside the Earth's atmosphere, such as stars, planets, comets, galaxies, and the cosmic background radiation. It is concerned with the formation and development of the universe, the evolution and physical and chemical properties of celestial objects and the calculation of their motions. Astronomical observations are not only relevant for astronomy as such, but provide essential information for the verification of fundamental theories in physics, such as general relativity theory. Complementary to observational astronomy, theoretical astrophysics seeks to explain astronomical phenomena. Astronomy is one of the oldest sciences, with a scientific methodology existing at the time of Ancient Greece and advanced observation techniques possibly much earlier (see archaeoastronomy). Historically, amateurs have contributed to many important astronomical discoveries, and astronomy is one of the few sciences where amateurs can still play an active role, especially in the discovery and observation of transient phenomena. Astronomy is not to be confused with astrology, which assumes that people's destiny and human affairs in general are correlated to the apparent positions of astronomical objects in the sky -- although the two fields share a common origin, they are quite different; astronomers embrace the scientific method, while astrologers do not. In other words, there is no proof that the stars predict our future, but there is proof that our planet is 93 million miles from the sun.

Divisions

In ancient Greece and other early civilizations, astronomy consisted largely of astrometry, measuring positions of stars and planets in the sky. Later, the work of Kepler and Newton, whose work led to the development of celestial mechanics, mathematically predicting the motions of celestial bodies interacting under gravity, and solar system objects in particular. Much of the effort in these two areas, once done largely by hand, is highly automated nowadays, to the extent that they are rarely considered as independent disciplines anymore. Motions and positions of objects are now more easily determined, and modern astronomy is more concerned with observing and understanding the actual physical nature of celestial objects. Since the twentieth century, the field of professional astronomy has split into observational astronomy and theoretical astrophysics. Although most astronomers incorporate elements of both into their research, because of the different skills involved, most professional astronomers tend to specialize in one or the other. Observational astronomy is concerned mostly with acquiring data, which involves building and maintaining instruments and processing the results; this branch is at times referred to as "astrometry" or simply as "astronomy". Theoretical astrophysics is concerned mainly with ascertaining the observational implications of different models, and involves working with computer or analytic models. The fields of study can also be categorized in other ways. Categorization by the region of space under study (for example, Galactic astronomy, Planetary Sciences); by subject, such as star formation or cosmology; or by the method used for obtaining information.

Ways of obtaining information

list of astronomical topics :Main article: Observational astronomy. In astronomy, information is mainly received from the detection and analysis of light and other forms of electromagnetic radiation. Other cosmic rays are also observed, and several experiments are designed to detect gravitational waves in the near future. A traditional division of astronomy is given by the region of the electromagnetic spectrum observed:
- Optical astronomy is the part of astronomy that uses optical components (mirrors, lenses, CCD detectors and photographic films) to observe light from near infrared to near ultraviolet wavelengths. Visible light astronomy (using wavelengths that can be detected with the eyes, about 400 - 700 nm) falls in the middle of this range. The most common tool is the telescope, with electronic imagers and spectrographs.
- Infrared astronomy deals with the detection and analysis of infrared radiation (wavelengths longer than red light). The most common tool is the telescope but using a detector which is sensitive to the infrared. Space telescopes are also used to avoid atmospheric thermal emission, atmospheric opacity, and the effects of astronomical seeing at infrared and other wavelengths.
- Radio astronomy detects radiation of millimetre to dekametre wavelength. The receivers are similar to those used in radio broadcast transmission but much more sensitive. See also Radio telescopes.
- High-energy astronomy includes X-ray astronomy, gamma-ray astronomy, and extreme UV (ultraviolet) astronomy, as well as studies of neutrinos and cosmic rays. Optical and radio astronomy can be performed with ground-based observatories, because the atmosphere is transparent at the wavelengths being detected. Infrared light is heavily absorbed by water vapor, so infrared observatories have to be located in high, dry places or in space. The atmosphere is opaque at the wavelengths of X-ray astronomy, gamma-ray astronomy, UV astronomy and (except for a few wavelength "windows") Far infrared astronomy, so observations must be carried out mostly from balloons or space observatories. Powerful gamma rays can, however be detected by the large air showers they produce, and the study of cosmic rays can also be regarded as a branch of astronomy.

History of astronomy

cosmic ray :Main article: History of astronomy. In early times, astronomy only comprised the observation and predictions of the motions of the naked-eye objects. Aristotle said that the Earth was the center of the Universe and everything rotated around it in orbits that were perfect circles. Aristotle had to be right because people thought that Earth had to be in the center with everything rotating around it because the wind would not scatter leaves, and birds would only fly in one direction. For a long time, people thought that Aristotle was right, but it is probable that Aristotle accidentally did more to hinder our knowledge than help it. The Rigveda refers to the 27 constellations associated with the motions of the sun and also the 12 zodiacal divisions of the sky. The ancient Greeks made important contributions to astronomy, among them the definition of the magnitude system. The Bible contains a number of statements on the position of the earth in the universe and the nature of the stars and planets, most of which are poetic rather than literal; see Biblical cosmology. In 500 AD, Aryabhata presented a mathematical system that described the earth as spinning on its axis and considered the motions of the planets with respect to the sun. Observational astronomy was mostly stagnant in medieval Europe, but flourished in the Iranian world and other parts of Islamic realm. The late 9th century Persian astronomer al-Farghani wrote extensively on the motion of celestial bodies. His work was translated into Latin in the 12th century. In the late 10th century, a huge observatory was built near Tehran, Persia (now Iran), by the Persian astronomer al-Khujandi, who observed a series of meridian transits of the Sun, which allowed him to calculate the obliquity of the ecliptic. Also in Persia, Omar Khayyám performed a reformation of the calendar that was more accurate than the Julian and came close to the Gregorian. Abraham Zacuto was responsible in the 15th century for the adaptations of astronomical theory for the practical needs of Portuguese caravel expeditions. During the Renaissance, Copernicus proposed a heliocentric model of the Solar System. His work was defended, expanded upon, and corrected by Galileo Galilei and Johannes Kepler. Galileo added the innovation of using telescopes to enhance his observations. Kepler was the first to devise a system that described correctly the details of the motion of the planets with the Sun at the center. However, Kepler did not succeed in formulating a theory behind the laws he wrote down. It was left to Newton's invention of celestial dynamics and his law of gravitation to finally explain the motions of the planets. Newton also developed the reflecting telescope. Stars were found to be faraway objects. With the advent of spectroscopy it was proved that they were similar to our own sun, but with a wide range of temperatures, masses, and sizes. The existence of our galaxy, the Milky Way, as a separate group of stars was only proven in the 20th century, along with the existence of "external" galaxies, and soon after, the expansion of the universe, seen in the recession of most galaxies from us. Modern astronomy has also discovered many exotic objects such as quasars, pulsars, blazars and radio galaxies, and has used these observations to develop physical theories which describe some of these objects in terms of equally exotic objects such as black holes and neutron stars. Physical cosmology made huge advances during the 20th century, with the model of the Big Bang heavily supported by the evidence provided by astronomy and physics, such as the cosmic microwave background radiation, Hubble's Law, and cosmological abundances of elements.

Stonehenge

Stonehenge is a Neolithic and Bronze Age monument located near Amesbury in the English county of Wiltshire, about 8 miles (13 km) northwest of Salisbury. It is composed of earthworks surrounding a circular setting of large standing stones, known as megaliths. There is some debate about the age of the stone circle, but most archaeologists think that it was mainly constructed between 2500 BC and 2000 BC. The older circular earth bank and ditch, which constitute perhaps the earliest phase of the monument, have been dated to about 3100 BC. The site and its surroundings were added to the UNESCO's list of World Heritage Sites in 1986. It is also a legally protected Scheduled Ancient Monument. The monument itself is owned and managed by English Heritage whilst the surrounding downland is owned by the National Trust. Stonehenge is located at .

Etymology

Christopher Chippendale's Stonehenge Complete gives the derivation of Stonehenge as being from the Old English words "stān" meaning "stone", and either "hencg" meaning "hinge" (because the stone lintels hinge on the upright stones) or "hen(c)en" meaning "gallows" or "instrument of torture". Medieval gallows consisted of two uprights with a lintel joining them rather than the inverted L-shape more familiar today. The "henge" portion has given its name to a class of monuments known as henges. Archaeologists define henges as earthworks consisting of a circular banked enclosure with an internal ditch. As often happens in archaeological terminology, this is a holdover from antiquarian usage, and Stonehenge cannot in fact be truly classified as a henge site as its bank is inside its ditch. Despite being contemporary with true Neolithic henges and stone circles, Stonehenge is in many ways atypical. For example, its extant trilithons make Stonehenge unique. Stonehenge is only distantly related to the other stone circles in the British Isles, such as the Ring of Brodgar.

Development of Stonehenge

Ring of Brodgar The Stonehenge complex was built in several construction phases spanning 2,000 years, although there is evidence for activity both before and afterwards on the site. Archaeologists have found three large Mesolithic postholes which date to around 8000 BC nearby, beneath the modern tourist car-park, and which may have had ritual significance, although there is no suggestion they are connected with the later monument. During the earlier Neolithic, a cursus monument was built 600m north of the site as the first farmers began to exploit the area. Later prehistoric pottery, Roman coins and the burial of a decapitated Saxon man have been excavated from Stonehenge, the last dated to the 7th century AD. Dating and understanding the various phases of activity at Stonehenge is not a simple task; it is complicated by poorly-kept early excavation records, surprisingly few accurate scientific dates and the disturbance of the natural chalk by periglacial effects and animal burrowing. The modern phasing most generally agreed by archaeologists is detailed below. Features mentioned in the text are numbered and shown on the plan, right, which illustrates the site as of AD 2004. The plan omits the trilithon lintels for clarity. Holes that no longer, or never, contained stones are shown as open circles and stones visible today are shown coloured.

Stonehenge 1

AD 2004 The first monument consisted of a circular bank and ditch enclosure (7 and 8) measuring around 115 m (320 feet) in diameter with a large entrance to the north east and a smaller one to the south (14). The builders placed bones of deer and oxen in the bottom of the ditch. These bones were considerably older than the antler picks used to dig the ditch and had been well looked-after for some time prior to burial. The ditch itself was continuous but had been dug in sections like the earlier causewayed enclosures and the chalk spoil piled up to form the bank. This first stage is dated to around 3100 BC after which the ditch began to silt up naturally. Within the outer edge of the enclosed area was dug a circle of 56 pits each around 1m in diameter (13), known as Aubrey holes after John Aubrey, the seventeenth century antiquarian who was thought to have first identified them. The pits may have contained standing timbers although there is no excavated evidence of them. A small outer bank beyond the ditch could also date to this period (9).

Stonehenge 2

Evidence of the second phase is no longer visible. It appears from the number of postholes dating to this period that some form of timber structure was built within the enclosure during the early 3rd millennium BC. Further standing timbers were placed at the northeast entrance and a parallel alignment of posts ran inwards from the southern entrance. The postholes are smaller than the Aubrey Holes, being only around 0.4m in diameter and are much less regularly spaced. The bank was purposely reduced in height and the ditch continued to silt up. At least twenty-five of the Aubrey Holes are known to have contained later, intrusive, cremation burials dating to the two centuries after the monument's inception. It seems that whatever the holes' initial function, it changed to become a funerary one during Phase 2. Thirty further cremations were placed in the enclosure's ditch and at other points within the monument, mostly in the eastern half. Stonehenge is therefore interpreted as functioning as an enclosed cremation cemetery at this time, the earliest known cremation cemetery in the British Isles. Fragments of unburnt human bone have also been found in the ditch fill. Late Neolithic grooved ware pottery has been found in connection with the features from this phase providing dating evidence.

Stonehenge 3i

Archaeological excavation has indicated that around 2600 BC, timber was abandoned in favour of stone and two concentric crescents of holes (called the Q and R Holes) were dug in the centre of the site. Again, there is little firm dating evidence for this phase. The holes held 80 standing bluestones (shown blue on the plan) brought from the Preseli Hills, 250 km away in modern day Pembrokeshire in Wales. The stones, which weighed about four tons, consisted mostly of spotted dolerite but included examples of rhyolite, tuff and volcanic and calcareous ash. Each measures around 2m in height, between 1m and 1.5m wide and around 0.8m thick. What was to become known as the Altar Stone (1), a six-ton specimen of green micaceous sandstone twice the height of the bluestones, was also brought from the Welsh coast near Preseli and may have stood as a single large monolith. The north eastern entrance was also widened at this time with the result that it precisely matched the direction of the midsummer sunrise and midwinter sunset of the period. This phase of the monument was abandoned unfinished however, the bluestones were apparently removed and the Q and R holes purposefully backfilled. Even so, the monument appears to have eclipsed the site at Avebury in importance towards the end of this phase and the Amesbury Archer, found in 2002 three miles (5 km) to the south, would have seen the site in this state. The Heel Stone (5) may also have been erected outside the north eastern entrance during this period although it cannot be securely dated and may have been installed at any time in phase 3. At first, a second stone, now no longer visible, joined it. Two, or possibly three, large portal stones were set up just inside the northeastern entrance of which only one, the fallen Slaughter Stone (4), 16 ft (4.9 m) long, now remains. Other features loosely dated to phase 3 include the four Station Stones (6), two of which stood atop mounds (2 and 3). The mounds are known as 'barrows' although they do not contain burials. The Avenue, (10), a parallel pair of ditches and banks leading 3 km to the River Avon was also added. Ditches were later dug around the Station Stones and the Heel Stone, which was by then reduced to a single monolith.

Stonehenge 3ii

The next major phase of activity at the tail end of the 3rd millennium BC saw 30 enormous Sarsen stones (shown grey on the plan) brought from a quarry around 24 miles (40 km) north to the site on the Marlborough Downs. The stones were dressed and fashioned with mortise and tenon joints before 30 were erected as a 33 m (108 ft) diameter circle of standing stones with a 'lintel' of 30 stones resting on top. The lintels themselves were joined to one another using another woodworking method, the tongue in groove joint . Each stone weighed around 25 tons and had clearly been worked with the final effect in mind. The orthostats widen slightly towards the top in order that their perspective remains constant as they rise up from the ground whilst the lintel stones curve slightly to continue the circular appearance of the earlier monument. The sides of the stones that face inwards are more finely worked than the sides that face outwards. A total of 74 stones would have been needed to complete the circle and unless some of the sarsens were removed from the site, it would seem that the ring was left incomplete. Within this circle stood five trilithons of dressed sarsen stone arranged in a horseshoe shape. These huge stones, ten uprights and five lintels, weigh up to 50 tons each and were again linked using complex jointings. The images of a 'dagger' and 14 'axe-heads' have been recorded carved on one of the sarsens, known as stone 53. Further axe-head carvings have been seen on the outer faces of stones known as numbers 3, 4, and 5. They are difficult to date but are morphologically similar to later Bronze Age weapons. The pair of trilithons in north east are smallest, measuring around 6m (20 feet) in height and the largest is the trilithon in the south west of the horseshoe is almost 7.5m (24 feet) tall. This ambitious phase is radiocarbon dated to between 2440 and 2100 BC.

Stonehenge 3iii

Later in the Bronze Age, the bluestones appear to have been re-erected for the first time although the precise details of this period are still unclear. They were placed within the outer sarsen circle and at this time may have been trimmed in some way. A few have timber working-style cuts in them like the sarsens themselves, suggesting they may have been linked with lintels and part of a larger structure during this phase.

Stonehenge 3iv

This phase saw further rearrangement of the bluestones as they were placed in a circle between the two settings of sarsens and in an oval in the very centre. Some archaeologists argue that some of the bluestones in this period were part of a second group brought from Wales. All the stones were well-spaced uprights without any linking lintels inferred in Stonehenge 3iii. The Altar Stone may have been moved within the oval and stood vertically. Although this would seem the most impressive phase of work, Stonehenge 3iv was rather shabbily built compared to its immediate predecessors, the newly re-installed bluestones were not at all well founded and began to fall over. However, only minor changes were made after this phase. Stonehenge 3iv dates from 2280 to 1930 BC.

Stonehenge 3v

Soon afterwards, the north eastern section of the Phase 3iv Bluestone circle was removed, creating a horseshoe-shaped setting termed the Bluestone Horseshoe. This mirrored the shape of the central sarsen Trilithons and dates from 2270 to 1930 BC. This phase is contemporary with the famous Seahenge site in Norfolk.

Stonehenge 3vi

Two further rings of pits were dug outside the outermost sarsen circle, called the Y and Z Holes (11 and 12). The Z holes were about 2m outside the outermost sarsen circle and the Y holes about 5m further out. These were each of thirty pits and each seems to match with one of the uprights in the outer sarsen circle. They were never filled with stones however and were permitted to silt up over the next few centuries; their upper fills contain Iron Age and Roman material. Monument building at Stonehenge appears to have been abandoned around 1600 BC.

Theories about Stonehenge

Early interpretations

1600 BC Many early historians were influenced by supernatural folktales in their explanations. Some legends held that Merlin the wizard had a giant build the structure for him or that he had magically transported it from Mount Killaraus in Ireland, while others held the Devil responsible. Henry of Huntingdon was the first to write of the monument around 1130 soon followed by Geoffrey of Monmouth who was the first to record fanciful associations with King Arthur which led the monument to be incorporated into the wider cycle of European medieval romance. In 1615, Inigo Jones argued that Stonehenge was a Roman temple, dedicated to 'Cnelus', a pagan god, and built following the Tuscan order. Later commentators maintained that the Danes erected it. Indeed, up until the late nineteenth century, the site was commonly attributed to the Saxons or other relatively recent societies. The first academic effort to survey and understand the monument was made around 1740 by William Stukeley. As was his wont, Stukeley incorrectly attributed the site to the Druids. He contributed measured drawings of the site, which permitted greater analysis of its form and significance. From this work he was able to demonstrate an astronomical or calendrical role in the stones' placement. By the turn of the nineteenth century, John Lubbock was able to attribute the site to the Bronze Age based on the bronze objects found in the nearby barrows.

Archaeoastronomy and Stonehenge

For further information, see Archaeoastronomy and Stonehenge. Stonehenge is aligned north east — south west, and it has been suggested that particular significance was placed by its builders on the solstice and equinox points, so for example on a midsummer's morning, the sun rose close to the Heel Stone, and the sun's first rays went directly into the centre of the monument between the horseshoe arrangement. It is unlikely that such an alignment can have been merely accidental. A huge debate was triggered by the 1963 publication of Stonehenge Decoded, by British born astronomer Gerald Hawkins, who claimed to see a large number of alignments, both lunar and solar, and argued that Stonehenge could have been used to predict eclipses. Hawkins' book received wide publicity, partly because he used a computer in his calculations, then a rarity. Archaeologists were suspicious in the face of further contributions to the debate coming from British astronomer C. A. Newham and Sir Fred Hoyle, the famous Cambridge Cosmologist, as well as by Alexander Thom, a retired professor of engineering, who had been studying stone circles for more than 20 years. Their theories have faced criticism in recent decades from Richard Atkinson and others who have suggested impracticalities in the 'Stone Age calculator' interpretative approach. Today, the consensus is that some of the astronomical case, although not all, was overstated. Even so, since the sun rises in different directions in different geographical latitudes, for the alignment to be correct, it must have been calculated precisely for Stonehenge's latitude of 51° 11'. This alignment, therefore, must have been fundamental to the design and placement of at least some of Stonehenge's phases. The recent discovery of a neighbour to the Heel Stone has challenged the interpretation of it as a midsummer sunrise marker and it may have instead been one side of a 'solar corridor' used to frame the sunrise. Sun worship is certainly not an uncommon phenomenon amongst Neolithic peoples given their reliance on it for crop fertility. Despite as many as 20,000 people visiting Stonehenge during the 2005 summer solstice, growing evidence indicates that ancestors did not visit at all in the summer, but rather during the winter solstice. The only megalithic monument in the British Isles to contain a clear, compelling solar alignment is Newgrange which famously faces the winter solstice sunrise. The most recent such evidence includes bones and teeth from pigs that were slaughtered at nearby Durrington Walls, their age at death indicating that they were slaughtered either in December or January every year. Mike Parker Pearson of the University of Sheffield has said "We have no evidence that anyone was in the landscape in summer." ^{[http://www.telegraph.co.uk/news/main.jhtml?xml=/news/2005/06/21/nsolst21.xml&sSheet=/portal/2005/06/21/ixportal.html]}

The bluestones

Roger Mercer has observed that the bluestones are incongruously finely worked and has suggested that they were transferred to Salisbury Plain from an as yet unlocated earlier monument in Pembrokeshire, Wales. If Mercer's theory is correct then the bluestones may have been transplanted to cement an alliance or display superiority over a conquered enemy although this can only be speculation. Oval shaped settings of bluestones similar to those at Stonehenge 3iv are also known at the sites of Bedd Arthur in the Preseli Hills and at Skomer Island off the southwest coast of Pembrokeshire. Some archaeologists have suggested that the igneous bluestones and sedimentary sarsens had some symbolism, of a union between two cultures from different landscapes and therefore from different backgrounds. Recent analysis of contemporary burials found nearby known as the Boscombe Bowmen, has indicated that at least some of the individuals associated with Stonehenge 3 did indeed come from modern day Wales. Petrological analysis of the stones themselves has verified that they could only have come from the Preseli Hills and it is tempting to connect the two. The main source of the bluestones is now identified with the dolerite outcrops at Carn Menyn although work led by Olwen Williams-Thorpe of the Open University has shown that further bluestone sources over a wider area of Preseli were also exploited. Aubrey Burl contends that the bluestones were not transported by human agency at all and were instead brought by glaciers at least part of the way from Wales during the Pleistocene. No geological evidence has been found for any glacial activity between Preseli and Salisbury Plain however and no further specimens of the unusual dolerite stone have been found in the vicinity.

Stonehenge as part of a ritual landscape

Pleistocene Many archaeologists believe Stonehenge was an attempt to render in permanent stone the more common timber structures that dotted Salisbury Plain at the time, such as those that stood at Durrington Walls. Modern anthropological evidence has been used by Mike Parker Pearson and the Madagascan archaeologist Ramilisonina to suggest that timber was associated with the living and stone with the ancestral dead. They have argued that Stonehenge was the terminus of a long, ritualised funerary procession, which began in the east at sunrise at Woodhenge and Durrington Walls, moved down the Avon and then along the Avenue reaching Stonehenge in the west at sunset. The journey from wood to stone via water was a symbolic journey from life to death. There is no satisfactory evidence to suggest that Stonehenge's astronomical alignments were anything more than symbolic and current interpretations favour a ritual role for the monument that takes into account its numerous burials and its presence within a wider landscape of sacred sites.

Construction techniques and design

Durrington Walls Durrington Walls Much speculation has surrounded the engineering feats required to build Stonehenge. Assuming the bluestones were brought from Wales by hand, and not transported by glaciers as Aubrey Burl has claimed, various methods of moving them relying only on timber and rope have been suggested. In a 2001 exercise in experimental archaeology, an attempt was made to transport a large stone along a land and sea route from Wales to Stonehenge. Volunteers pulled it on a wooden sledge over land, but once transferred to a replica prehistoric boat, the stone sank in rough seas of the Bristol Channel. As far as positioning the stones, it has been suggested that timber A frames were erected to raise the stones, and that teams of people then hauled them upright using ropes. The topmost stones may have been raised up incrementally on timber platforms and slid into place or pushed up ramps. The carpentry-type joints used on the stones imply a people well skilled in woodworking. They could easily have had the knowledge to erect the monument using such methods. Alexander Thom was of the opinion that the site was laid out with the necessary precision using his megalithic yard. The engraved weapons on the sarsens are unique in megalithic art in the British Isles, where more abstract designs were favoured. Similarly, the horseshoe arrangements of stones are unusual in a culture that otherwise arranged stones in circles. The axe motif is, however, common to the peoples of Brittany at the time, and it has been suggested at least two stages of Stonehenge were built under continental influence. This would go some way towards explaining the monument's atypical design, but overall, Stonehenge is still inexplicably unusual in the context of any prehistoric European culture. Estimates of the manpower needed to build Stonehenge put the total effort involved at millions of hours of work. Stonehenge 1 probably needed around 11,000 hours work, Stonehenge 2 around 360,000 and the various parts of Stonehenge 3 may have involved up to 1.75 million hours work. The working of the stones is estimated to have required around 20 million hours work using the primitive tools available at the time. Certainly, the will to produce such a site must have been strong, and it is considered that advanced social organisation would have been necessary to build and maintain it.

Alternative views

Stonehenge's fame comes not only from its archaeological significance or potential early astronomical role but also in its less tangible effect on visitors, what Christopher Chippindale describes as "the physical sensation of the place", something that transcends the rational, scientific view of the monument. This manifests itself in the spiritual role of the site for many different groups and a belief that no single scientific explanation can do justice to it as a symbol of the great achievement of ancient people and as a symbol of something that continues to confound mainstream archaeology. Post-processualist archaeologists might consider that treating Stonehenge as a computer or observatory is to apply modern concepts from our own technology-driven era back into the past.
