Siwa Oasis

Siwa Oasis is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Siwa Oasis rather than just read about it. In short: The Siwa Oasis (Arabic: واحة سيوة Wāḥat Sīwah [ˈwæːħet ˈsiːwæ]) is an urban oasis in Egypt. It is situated between the Qattara Depression and the Great Sand Sea in the Western Desert, 50 kilometres (31 mi) east of the Egypt–Libya border and 560 kilometres (350 mi) from the Egyptian capital city of Cairo.

Key takeaways

  • Siwa Oasis belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Siwa Oasis to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Siwa Oasis from memory before moving on to harder problems.

Reference excerpt

The Siwa Oasis (Arabic: واحة سيوة Wāḥat Sīwah [ˈwæːħet ˈsiːwæ]) is an urban oasis in Egypt. It is situated between the Qattara Depression and the Great Sand Sea in the Western Desert, 50 kilometres (31 mi) east of the Egypt–Libya border and 560 kilometres (350 mi) from the Egyptian capital city of Cairo. It is famed for its role in ancient Egypt as the home to an oracle of Amun, the ruins of which are a popular tourist attraction, giving it the ancient name Oasis of Amun-Ra, after the major Egyptian deity.

Geography The oasis is in a deep depression that reaches −19 metres (−62 ft) below sea level. To the west, the al Jaghbub Oasis rests in a similar depression and to the east, the large Qattara Depression is also below sea level. The depression is fertile due to both natural flowing artesian wells and irrigation. It is the site of about 200 natural springs. Siwa is directly adjacent to the Libyan Desert plateau. The geology is characterised by horizontal layers of porous limestones alternated with marls and clays dating back to the Miocene. The limestone plateau and inselbergs resulting from the oasis' erosion along the dunes create reliefs that the Isiwan describe as mountains (adrar in Tamazight). Two large salt lakes are fed by drainage water of agricultural origin. The oasis supports the cultivation of thousands of date palms and olives. Siwa has a temperate desert climate.

Name

The Ancient Egyptian name of the oasis was sḫt jꜣmw, meaning "Field of Trees". The native Libyan toponym may be preserved in the Egyptian t̠ꜣ(j) n d̠rw "tꜣj on the fringe" where t̠ꜣ transcribed the local Palaeo-Berber name *Se or *Sa. This name survived in the works of Muslim geographers as سنترية Santariyyah. Siwah is the Arabic name of the oasis called Sali in Berber. The oasis is also called Isiwan in modern Berber. The etymology of the word سيوة Siwah is unclear. Champollion derives it from Coptic ⲥⲟⲟⲩϩ (soouh) – a corruption of the Egyptian word for "oasis", ⲟⲩⲁϩ (ouoh). The additional evidence of the Egyptian source of Siwa's name is another place name in Kharga Oasis that may share the same etymology – S.t-wȝḥ, modern Deir el-Hagar). Basset links it to a Berber tribal name swh attested further west in the early Islamic period, while Ilahiane, following Chafik, links it to the Shilha Berber word asiwan, a type of bird of prey, and hence to Amun-Ra, one of whose symbols was the falcon. Some classical authors referred to the site as "Ammonium".

History Although the site is known to have been settled since at least the 10th millennium BCE, the earliest evidence of any connection with Ancient Egypt is the 26th Dynasty, when a necropolis was established. Ancient Greek settlers at Cyrene made contact with the oasis around the same time (7th century BCE), and the oracle temple of Amun (Greek: Zeus Ammon), who, Herodotus was told, took the image here of a ram. Herodotus knew of a "fountain of the Sun" that ran coldest in the noontime heat. During his campaign to conquer the Persian Empire, Alexander the Great reached the oasis, supposedly by following birds across the desert. The oracle, Alexander's court historians alleged, confirmed him as both a divine personage and the legitimate Pharaoh of Egypt, though Alexander's motives in making the excursion, following his founding of Alexandria, remain to some extent inscrutable and contested. During the Ptolemaic Kingdom, its Ancient Egyptian name was sḫ.t-ỉm3w, meaning "Field of Trees".

In the 12th century, Al-Idrisi mentions it as being inhabited mainly by Berbers, with an Arab minority; a century earlier, Al-Bakri stated that only Berbers lived there. The Egyptian historian Al-Maqrizi travelled to Siwa in the 15th century and described how the language spoken there 'is similar to the language of the Zenata'. The first European to document a visit since Roman times was the English traveller William George Browne, who came in 1792 to see the ancient temple of the Oracle of Amun. Bompiani, in her description of the 19th-century explorer Luigi Robecchi Bricchetti, called this site the Oasis of Jupiter Ammon. Siwa was annexed by Muhammad Ali of Egypt in 1820, but the Egyptian representative in Siwa was assassinated in 1838. At some point, Muhammad al-Sanusi stayed at Siwa for a few months and gathered some followers there. Later, Siwa was a base of the Sanusiyya in their fight against the British from 1915 to 1917. Meanwhile, in the spring of 1893, German explorer and photographer Hermann Burchardt took photographs of the architecture of the town of Siwa, now stored at the Ethnological Museum of Berlin. Egyptian rule from distant Cairo was at first tenuous and marked by several revolts. Egypt began to assert firmer control after a 1928 visit to the oasis by King Fuad I, who berated the locals for homosexual practices and specified punishments to bring Siwan behaviour in line with Egyptian morals.

Worked examples

Example 1 — a first encounter with Siwa Oasis

Start with the simplest possible case. Write down what Siwa Oasis claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Siwa Oasis before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Siwa Oasis ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Siwa Oasis

In research
Siwa Oasis appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Siwa Oasis in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Siwa Oasis is common in secondary-school and first-year university syllabi. It links to neighbouring topics Berber populated places, Berbers in Egypt, Cities in Egypt, so understanding it makes those chapters shorter.
In everyday life
Look for Siwa Oasis outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
