Al-Battani
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 obscur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arab
The Arabs (singular: Arab; singular ar, عَرَبِيٌّ, DIN 31635: , , plural ar, عَرَب, DIN 31635: , Arabic pronunciation: ), also known as the Arab people, are an ethnic group mainly inhabiting the Arab world in Western Asia, North Africa, the Horn of Africa, and the western Indian Ocean islands (including the Comoros). An Arab diaspora is also present around the world in significant numbers, most notably in the Americas, Western Europe, Turkey, Indonesia, and Iran. In modern usage, the term "Arab" tends to refer to those who both carry that ethnic identity and speak Arabic as their native language. This contrasts with the narrower traditional definition, which refers to the descendants of the tribes of Arabia. The religion of Islam was developed in Arabia, and Classical Arabic serves as the language of Islamic literature. 93 percent of Arabs are Muslims (the remainder consisted mostly of Arab Christians), while Arab Muslims are only 20 percent of the ...

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 ...

Abū Al-Wafā'
Abū al-Wafāʾ, Muḥammad ibn Muḥammad ibn Yaḥyā ibn Ismāʿīl ibn al-ʿAbbās al-Būzjānī or Abū al-Wafā Būzhjānī ( fa, ابوالوفا بوزجانی or بوژگانی) (10 June 940 – 15 July 998) was a Persian mathematician and astronomer who worked in Baghdad. He made important innovations in spherical trigonometry, and his work on arithmetics for businessmen contains the first instance of using negative numbers in a medieval Islamic text. He is also credited with compiling the tables of sines and tangents at 15 ' intervals. He also introduced the secant and cosecant functions, as well studied the interrelations between the six trigonometric lines associated with an arc. His ''Almagest'' was widely read by medieval Arabic astronomers in the centuries after his death. He is known to have written several other books that have not survived.

Harran
Harran (), historically known as Carrhae ( el, Kάρραι, Kárrhai), is a rural town and district of the Şanlıurfa Province in southeastern Turkey, approximately 40 kilometres (25 miles) southeast of Urfa and 20 kilometers from the border crossing with Syria at Akçakale. Harran was founded at some point between the 25th and 20th centuries BC as a merchant colony by Sumerian traders from Ur. Over the course of its early history, Harran rapidly grew into a major Mesopotamian cultural, commercial and religious center. It was made a religiously and politically influential city through its association with the moon-god Sin; many prominent Mesopotamian rulers consulted with and renovated the moon-temple of Ekhulkhul in Harran. Harran came under Assyrian rule under Adad-nirari I ( BC) and became a provincial capital often second in importance only to the Assyrian capital of Assur itself. During the collapse of the Assyrian Empire, Harran briefly served as the final capital of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Astronomy
Astronomy () is a natural science that studies astronomical object, celestial objects and phenomena. It uses mathematics, physics, and chemistry in order to explain their origin and chronology of the Universe, evolution. Objects of interest include planets, natural satellite, moons, stars, nebulae, galaxy, galaxies, and comets. Relevant phenomena include supernova explosions, gamma ray bursts, quasars, blazars, pulsars, and cosmic microwave background radiation. More generally, astronomy studies everything that originates beyond atmosphere of Earth, Earth's atmosphere. Cosmology is a branch of astronomy that studies the universe as a whole. Astronomy is one of the oldest natural sciences. The early civilizations in recorded history made methodical observations of the night sky. These include the Babylonian astronomy, Babylonians, Greek astronomy, Greeks, Indian astronomy, Indians, Egyptian astronomy, Egyptians, Chinese astronomy, Chinese, Maya civilization, Maya, and many anc ...

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 ().
