The Faiyum Oasis (or Al-Fayoum Oasis, Al Fayyum Oasis, and other variations in spelling) is a depression or basin in the desert immediately to the west of the Nile south of Cairo. The extent of the basin area is estimated at between 1,270 km² (490 mi²) and 1700 km² (656 mi²). The basin floor comprises fields watered by a channel of the Nile, the Bahr Yussef, as it drains into a desert depression to the west of the Nile Valley. The Bahr Yussef veers west through a narrow neck of land north of Ihnasya, between the archaeological sites of El-Lahun and Gurob near Hawara; it then branches out, providing rich agricultural land in the Faiyum basin, draining into the large saltwater Lake Moeris (Birket Qarun). The lake was freshwater in prehistory but is today a saltwater lake. It is a source for tilapia and other fish for the local area. Differing from typical oases, whose fertility depends on water obtained from springs, the cultivated land in the Faiyum is formed of Nile mud brought down by the Bahr Yussef, 24 km (15 miles) in length. Between the beginning of Bahr Yussef at El-Lahun to its end at the city of Faiyum, several canals branch off to irrigate the Faiyum Governorate. The drainage water flows into Lake Moeris. Over 1,000 km² (400 mile²) of the Faiyum Oasis is cultivated, the chief crops being cereals and cotton. The completion of the Aswan Low Dam ensured a fuller supply of water, which enabled 20,000 acres (80 km²) of land, previously unirrigated and untaxed, to be brought under cultivation in the three years 1903-1905. Three crops are obtained in twenty months. The province is noted for its figs and grapes of exceptional quality. Olives are also cultivated. Rose trees are very numerous, and most of the attar of roses of Egypt is manufactured in the province. Faiyum also possesses an excellent breed of sheep. ==History== When the Mediterranean Sea was a hot dry hollow near the end of the Messinian Salinity Crisis in the late Miocene, Faiyum was a dry hollow, and the Nile flowed past it at the bottom of a canyon (which was 8000 feet deep or more where Cairo is today). After the Mediterranean reflooded at the end of the Miocene, the Nile canyon became an arm of the sea reaching inland further than Aswan. Over geological time that sea arm gradually filled with silt and became the Nile valley. Eventually the Nile valley bed silted up high enough to let the Nile in flood overflow into the Faiyum hollow and make a lake in it. The lake is first recorded from about 3000 BC, around the time of Menes (Narmer). However, for the most part it would only be filled with high flood waters. The lake was bordered by neolithic settlements, and the town of Crocodilopolis grew up on the south where the higher ground created a ridge. In 2300 BC, the waterway from the Nile to the natural lake was widened and deepened to make a canal which is now known as the Bahr Yussef. This canal fed into the lake. This was meant to serve three purposes: control the flooding of the Nile, regulate the water level of the Nile during dry seasons, and serve the surrounding area with irrigation. There is evidence of ancient Egyptian pharaohs of the twelfth dynasty using the natural lake of Faiyum as a reservoir to store surpluses of water for use during the dry periods. The immense waterworks undertaken by the ancient Egyptian pharaohs of the twelfth dynasty to transform the lake into a huge water reservoir gave the impression that the lake itself was an artificial excavation, as reported by classic geographers and travellers.〔(Catholic Encyclopedia: Egypt )〕 The lake was eventually abandoned due to the nearest branch of the Nile dwindling in size from 230 BC. Faiyum was known to the ancient Egyptians as the twenty-first nome of Upper Egypt, Atef-Pehu ("Northern Sycamore"). In ancient Egyptian times, its capital was Sh-d-y-t (usually written "Shedyt"),〔Hieroglyphic writing did not have vowels, so spellings vary as to use of vowels for names in Egyptian culture. Hieroglyphic pronunciation was indicated by determinatives which showed what sort of meaning the word had.〕 called by the Greeks Crocodilopolis, and refounded by Ptolemy II as Arsinoe. This region has the earliest evidence for farming in Egypt, and was a center of royal pyramid and tomb-building in the Twelfth dynasty of the Middle Kingdom, and again during the rule of the Ptolemaic dynasty. Faiyum became one of the breadbaskets of the Roman world. For the first three centuries AD, the people of Faiyum and elsewhere in Roman Egypt not only embalmed their dead but also placed a portrait of the deceased over the face of the mummy wrappings, shroud or case. The Egyptians continued their practice of burying their dead, despite the Roman preference for cremation. Preserved by the dry desert environment, these Faiyum portraits make up the richest body of portraiture to have survived from antiquity. They provide us with a window into a remarkable society of peoples of mixed origins —Egyptians, Greeks, Romans, Syrians, Libyans and others — that flourished 2,000 years ago in Faiyum. The Faiyum portraits were painted on wood in a pigmented wax technique called encaustic.〔(History of Encaustic Art )〕 In the late 1st millennium AD, the arable area shrank, and settlements around the edge of the basin were abandoned. These sites include some of the best-preserved from the late Roman Empire, notably Karanis, and from the Byzantine and early Arab Periods, though recent redevelopment has greatly reduced the archaeological features. For late-period Ancient Egyptian names of the Faiyum oasis and places within it, see http://fayum.arts.kuleuven.be/general/name.html . "Colonial-type" village names (villages named after towns elsewhere in Egypt and places outside Egypt) show that much land was brought into cultivation in the Faiyum in the Greek and Roman periods. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Faiyum Oasis」の詳細全文を読む スポンサード リンク
