Albategnius
Abū ʿAbd Allāh Muḥammad ibn Jābir ibn Sinān al-Raqqī al-Ḥarrānī aṣ-Ṣābiʾ al-Battānī ( ar, محمد بن جابر بن سنان البتاني) ( Latinized as Albategnius, Albategni or Albatenius) (c. 858 – 929) was an astronomer and mathematician from Harran. He introduced a number of trigonometric relations, and his ''Kitāb az-Zīj'' was frequently quoted by many medieval astronomers, including Copernicus. Often called the "Ptolemy of the Arabs", al-Battani is perhaps one of the greatest and best known astronomer of the medieval Islamic world. Life Little of al-Battānī's life is known other than his birthplace in Harran near Urfa, in Upper Mesopotamia, (today in Turkey) and his father's fame as a maker of scientific instruments. Jabir ibn Sinan al-Harrani was likely this famous instrument maker, although this is not something that has been proven. His epithet ''aṣ-Ṣabi’'' suggests that his family belonged to the Sabian religion of Harran, an obscure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Islamic Astronomy
Islamic astronomy comprises the Astronomy, astronomical developments made in the Islamic world, particularly during the Islamic Golden Age (9th–13th centuries), and mostly written in the Arabic language. These developments mostly took place in the Middle East, Central Asia, Al-Andalus, and North Africa, and later in the Far East and History of India, India. It closely parallels the genesis of other Islamic sciences in its assimilation of foreign material and the amalgamation of the disparate elements of that material to create a science with Islamic characteristics. These included Greek astronomy, Greek, Sassanid Empire, Sassanid, and Indian astronomy, Indian works in particular, which were translated and built upon. Islamic astronomy played a significant role in the revival of Byzantine science, Byzantine and Science in Medieval Western Europe, EuropeanSaliba (1999). astronomy following the Dark Ages (historiography), loss of knowledge during the early medieval period, notably ...

Astrolabe
An astrolabe ( grc, ἀστρολάβος ; ar, ٱلأَسْطُرلاب ; persian, ستارهیاب ) is an ancient astronomical instrument that was a handheld model of the universe. Its various functions also make it an elaborate inclinometer and an analog calculation device capable of working out several kinds of problems in astronomy. In its simplest form it is a metal disc with a pattern of wires, cutouts, and perforations that allows a user to calculate astronomical positions precisely. Historically used by astronomers, it is able to measure the altitude above the horizon of a celestial body, day or night; it can be used to identify stars or planets, to determine local latitude given local time (and vice versa), to survey, or to triangulate. It was used in classical antiquity, the Islamic Golden Age, the European Middle Ages and the Age of Discovery for all these purposes. The astrolabe's importance comes not only from the early developments into the study of astron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Latinization (literature)
Latinisation (or Latinization) of names, also known as onomastic Latinisation, is the practice of rendering a ''non''-Latin name in a Latin style. It is commonly found with historical proper names, including personal names and toponyms, and in the standard binomial nomenclature of the life sciences. It goes further than romanisation, which is the transliteration of a word to the Latin alphabet from another script (e.g. Cyrillic). For authors writing in Latin, this change allows the name to function grammatically in a sentence through declension. In a scientific context, the main purpose of Latinisation may be to produce a name which is internationally consistent. Latinisation may be carried out by: * transforming the name into Latin sounds (e.g. for ), or * adding Latinate suffixes to the end of a name (e.g. for '' Meibom),'' or * translating a name with a specific meaning into Latin (e.g. for Italian ; both mean 'hunter'), or * choosing a new name based on some attribute ...

Raqqa
Raqqa ( ar, ٱلرَّقَّة, ar-Raqqah, also and ) (Kurdish languages, Kurdish: Reqa/ ڕەقە) is a city in Syria on the northeast bank of the Euphrates River, about east of Aleppo. It is located east of the Tabqa Dam, Syria's largest dam. The Hellenistic, Roman, and Byzantine city and bishopric Callinicum (formerly a Latin and now a Maronite Catholic titular see) was the capital of the Abbasid Caliphate between 796 and 809, under the reign of Harun al-Rashid.

Encyclopædia Britannica Eleventh Edition
The ''Encyclopædia Britannica'' Eleventh Edition (1910–1911) is a 29-volume reference work, an edition of the ''Encyclopædia Britannica''. It was developed during the encyclopaedia's transition from a British to an American publication. Some of its articles were written by the best-known scholars of the time. This edition of the encyclopaedia, containing 40,000 entries, has entered the public domain and is easily available on the Internet. Its use in modern scholarship and as a reliable source has been deemed problematic due to the outdated nature of some of its content. Modern scholars have deemed some articles as cultural artifacts of the 19th and early 20th centuries. Background The 1911 eleventh edition was assembled with the management of American publisher Horace Everett Hooper. Hugh Chisholm, who had edited the previous edition, was appointed editor in chief, with Walter Alison Phillips as his principal assistant editor. Originally, Hooper bought the rights to th ...

Muslim
Muslims ( ar, المسلمون, , ) are people who adhere to Islam, a monotheistic religion belonging to the Abrahamic tradition. They consider the Quran, the foundational religious text of Islam, to be the verbatim word of the God of Abraham (or '' Allah'') as it was revealed to Muhammad, the main Islamic prophet. The majority of Muslims also follow the teachings and practices of Muhammad ('' sunnah'') as recorded in traditional accounts (''hadith''). With an estimated population of almost 1.9 billion followers as of 2020 year estimation, Muslims comprise more than 24.9% of the world's total population. In descending order, the percentage of people who identify as Muslims on each continental landmass stands at: 45% of Africa, 25% of Asia and Oceania (collectively), 6% of Europe, and 1% of the Americas. Additionally, in subdivided geographical regions, the figure stands at: 91% of the Middle East–North Africa, 90% of Central Asia, 65% of the Caucasus, 42% of Southeast As ...

Star Worship
Astrotheology, astral mysticism, astral religion, astral or stellar theology (also referred to as astral or star worship) is the worship of the stars (individually or together as the night sky), the planets, and other heavenly bodies as deities, or the association of deities with heavenly bodies. In anthropological literature these systems of practice may be referred to as astral cults. The most common instances of this are sun gods and moon gods in polytheistic systems worldwide. Also notable is the association of the planets with deities in Babylonian, and hence in Greco-Roman religion, viz. Mercury, Venus, Mars, Jupiter and Saturn. Gods, goddesses, and demons may also be considered personifications of astronomical phenomena such as lunar eclipses, planetary alignments, and apparent interactions of planetary bodies with stars. The Sabians of Harran, a poorly understood pagan religion that existed in Harran during the early Islamic period (7th–10th century), were known for t ...

Sabians
The Sabians, sometimes also spelled Sabaeans or Sabeans, are a mysterious religious group mentioned three times in the Quran (as , in later sources ), where it is implied that they belonged to the 'People of the Book' (). Their original identity, which seems to have been forgotten at an early date, has been called an "unsolved Quranic problem". Modern scholars have variously identified them as Mandaeans, Manichaeans, Sabaeans, Elchasaites, Archontics, (either as a type of Gnostics or as "sectarians"), or as adherents of the astral religion of Harran. Some scholars believe that it is impossible to establish their original identity with any degree of certainty. At least from the ninth century on, the Quranic epithet 'Sabian' was claimed by various religious groups who sought recognition by the Muslim authorities as a People of the Book deserving of legal protection (). Among those are the Sabians of Harran, adherents of a poorly understood pagan religion centered in the upper ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mesopotamia
Mesopotamia ''Mesopotamíā''; ar, بِلَاد ٱلرَّافِدَيْن or ; syc, ܐܪܡ ܢܗܪ̈ܝܢ, or , ) is a historical region of Western Asia situated within the Tigris–Euphrates river system, in the northern part of the Fertile Crescent. Today, Mesopotamia occupies modern Iraq. In the broader sense, the historical region included present-day Iraq and Kuwait and parts of present-day Iran, Syria and Turkey. The Sumerians and Akkadians (including Assyrians and Babylonians) originating from different areas in present-day Iraq, dominated Mesopotamia from the beginning of written history () to the fall of Babylon in 539 BC, when it was conquered by the Achaemenid Empire. It fell to Alexander the Great in 332 BC, and after his death, it became part of the Greek Seleucid Empire. Later the Arameans dominated major parts of Mesopotamia (). Mesopotamia is the site of the earliest developments of the Neolithic Revolution from around 10,000 BC. It has been identi ...

Urfa
Urfa, officially known as Şanlıurfa () and in ancient times as Edessa, is a city in southeastern Turkey and the capital of Şanlıurfa Province. Urfa is situated on a plain about 80 km east of the Euphrates River. Its climate features extremely hot, dry summers and cool, moist winters. About northeast of the city is the famous Neolithic site of Göbekli Tepe, the world's oldest known temple, which was founded in the 10th millennium BC. The area was part of a network of the first human settlements where the agricultural revolution took place. Because of its association with Jewish, Christian, and Islamic history, and a legend according to which it was the hometown of Abraham, Urfa is nicknamed the "City of Prophets." Religion is important in Urfa. The city "has become a center of fundamentalist Islamic beliefs" and "is considered one of the most devoutly religious cities in Turkey".
