Azophi (crater)
–
Azophi is a lunar impact crater that lies in the rugged south-central highlands of the Moon. The northwest rim is attached to the smaller crater Abenezra. To the east-southeast is the large and irregular Sacrobosco, the wide outer rim of Azophi has a somewhat polygonal shape with rounded corners. The edge is sharp and cleft-like. The rim is not significantly worn or impacted by smaller craters, with the exception of Azophi C, the interior floor lacks a central peak and is only marked by a few tiny craterlets. It is named after the 10th-century Persian astronomer Abd Al-Rahman Al Sufi, also known by his western name, by convention these features are identified on lunar maps by placing the letter on the side of the crater midpoint that is closest to Azophi. 12621 Alsufi, asteroid named after Al Sufi

Rey, Iran
–
Rey or Ray, also known as Rhages and formerly as Arsacia, is the capital of Rey County in Tehran Province of Iran, and the oldest existing city in the province.

Note on spelling, According to the Iranian Chamber Society, the spelling of the city in both English and Persian is Ray, though variations in spelling also exist. The city university also uses the spelling Ray, as does the Encyclopædia Iranica published by Columbia University, a settlement began here c 6,000 BCE as part of the Central Plateau Culture. The settlement was used as a capital by the Arsacids called Rhaga, in Classical Greco-Roman geography it was called Rhagae. It is mentioned several times in the Apocrypha and its name dates back to the pre-Median period. Some historians attribute its building to ancient mythological monarchs, and some believe that Ray was the seat of a dynasty of Zoroastrian leader. During the Seleucid period, Alexander the Greats general Seleucus I Nicator renamed the city as Europos, Rey is also shown on the 4th century Peutinger Map. It has been home to pillars of science like Rhazes, Rey was one of the capital cities of the Seljuq Empire in the 11th century. In the 13th century after the Mongol conquest the town was severely damaged, there is also a shrine there, dedicated to commemorate Princess Shahr Banu, eldest daughter of the last ruler of the Sassanid Empire. She gave birth to Ali Zayn al Abidin, the fourth holy Imam of the Shia faith and this was through her marriage to Husayn ibn Ali, the grandson of Muhammad, the prophet of Islam. A nearby mountain is named after her. In the middle of the 19th century Ray was described as place of ruins, being the only important pilgrimage site in vicinity to the royal court in the new capital Tehran brought more people to visit the shrine and a major restoration was sponsored by the court. Thus Ray was the first place in Iran to be connected to the capital by a railroad in 1888, the shrine contains the tomb of ‘Abdul ‘Adhīm ibn ‘Abdillāh al-Hasanī, a fifth generation descendant of Hasan ibn ‘Alī and a companion of Muhammad al-Taqī. He was entombed here after his death in the 9th century, some of the discovered objects are displayed at museums in Iran, Chicago, and Philadelphia. The hill, which is now leveled out and most artifacts unrecoverable due to real estate expansion in the 1980s and 1990s, was the home of Aryans about 6,000 years ago. Since Ray was used as a center due to its beautiful attractions under the reign of the Qajar dynasty. In 1831 his portrait and that of some Qajar princes were engraved on a rock at Cheshmeh Ali hill, Tuğrul Tower, constructed under the Seljuqs at the order of Tuğrul Beg in 1140, once he transferred the capital city from Nishapur to Ray

Isfahan
–
Isfahan, historically also rendered in English as Ispahan, Sepahan, Esfahan or Hispahan, is the capital of Isfahan Province in Iran, located about 340 kilometres south of Tehran. The Greater Isfahan Region had a population of 3,793,104 in the 2011 Census, the counties of Isfahan, Borkhar, Najafabad, Khomeynishahr, Shahinshahr, Mobarakeh, Falavarjan, Tiran o Karvan, Lenjan and Jay all constitute the metropolitan city of Isfahan. Isfahan is located on the main north–south and east–west routes crossing Iran and it flourished from 1050 to 1722, particularly in the 16th and 17th centuries under the Safavid dynasty, when it became the capital of Persia for the second time in its history. Even today, the city retains much of its past glory and it is famous for its Persian–Islamic architecture, with many beautiful boulevards, covered bridges, palaces, mosques, and minarets. This led to the Persian proverb Esfahān nesf-e- jahān ast, the Naghsh-e Jahan Square in Isfahan is one of the largest city squares in the world. It has been designated by UNESCO as a World Heritage Site, the city also has a wide variety of historic monuments and is known for the paintings, history and architecture. Isfahan City Center is also the 5th largest shopping mall in the world, see also, Names of Isfahan The name of the region derives from Middle Persian Spahān. Spahān is attested in various Middle Persian seals and inscriptions, including that of Zoroastrian Magi Kartir, the present-day name is the Arabicized form of Ispahan. The region appears with the abbreviation GD on Sasanian numismatics, in Ptolemys Geographia it appears as Aspadana, translating to place of gathering for the army. It is believed that Spahān derives from spādānām the armies, Old Persian plural of spāda, the history of Isfahan can be traced back to the Palaeolithic period. In recent discoveries, archaeologists have found artifacts dating back to the Palaeolithic, Mesolithic, Neolithic, Bronze and Iron ages. It is said that after Cyrus the Great freed the Jews from Babylon some Jews returned to Jerusalem whereas some others decided to live in Persia, but, actually this happened later in the Sasanid period when a Jewish colony was made in the vicinity of the Sasanid. They did not settle anywhere or in any city without examining the water. They did all along until they reached the city of Isfahan, there they rested, examined the water and soil and found that both resembled Jerusalem. Upon they settled there, cultivated the soil, raised children and grandchildren, under the Parthians, Arsacid governors administered a large province from Isfahan, and the citys urban development accelerated to accommodate the needs of a capital city. The next empire to rule Persia, the Sassanids, presided over changes in their realm, instituting sweeping agricultural reform and reviving Iranian culture. The city was called by the name and the region by the name Aspahan or Spahan. The city was governed by Espoohrans or the members of seven noble Iranian families who had important royal positions, extant foundations of some Sassanid-era bridges in Isfahan suggest that the kings were also fond of ambitious urban planning projects

Astronomer
–
An astronomer is a scientist in the field of astronomy who concentrates their studies on a specific question or field outside of the scope of Earth. They look at stars, planets, moons, comets and galaxies, as well as other celestial objects — either in observational astronomy. Examples of topics or fields astronomers work on include, planetary science, solar astronomy, there are also related but distinct subjects like physical cosmology which studies the Universe as a whole. Astronomers usually fit into two types, Observational astronomers make direct observations of planets, stars and galaxies, and analyze the data, theoretical astronomers create and investigate models of things that cannot be observed. They use this data to create models or simulations to theorize how different celestial bodies work, there are further subcategories inside these two main branches of astronomy such as planetary astronomy, galactic astronomy or physical cosmology. Today, that distinction has disappeared and the terms astronomer. Professional astronomers are highly educated individuals who typically have a Ph. D. in physics or astronomy and are employed by research institutions or universities. They spend the majority of their time working on research, although quite often have other duties such as teaching, building instruments. The number of astronomers in the United States is actually quite small. The American Astronomical Society, which is the organization of professional astronomers in North America, has approximately 7,000 members. This number includes scientists from other such as physics, geology. The International Astronomical Union comprises almost 10,145 members from 70 different countries who are involved in research at the Ph. D. level. Before CCDs, photographic plates were a method of observation. Modern astronomers spend relatively little time at telescopes usually just a few weeks per year, analysis of observed phenomena, along with making predictions as to the causes of what they observe, takes the majority of observational astronomers time. Astronomers who serve as faculty spend much of their time teaching undergraduate and graduate classes, most universities also have outreach programs including public telescope time and sometimes planetariums as a public service to encourage interest in the field. Those who become astronomers usually have a background in maths, sciences. Taking courses that teach how to research, write and present papers are also invaluable, in college/university most astronomers get a Ph. D. in astronomy or physics. Keeping in mind how few there are it is understood that graduate schools in this field are very competitive

Islamic Golden Age
–
This period is traditionally said to have ended with the collapse of the Abbasid caliphate due to Mongol invasions and the Sack of Baghdad in 1258 AD. A few contemporary scholars place the end of the Islamic Golden Age as late as the end of 15th to 16th centuries, the metaphor of a golden age began to be applied in 19th-century literature about Islamic history, in the context of the western aesthetic fashion known as Orientalism. There is no definition of term, and depending on whether it is used with a focus on cultural or on military achievement. During the early 20th century, the term was used only occasionally, the Muslim government heavily patronized scholars. The money spent on the Translation Movement for some translations is estimated to be equivalent to twice the annual research budget of the United Kingdom’s Medical Research Council. The best scholars and notable translators, such as Hunayn ibn Ishaq, had salaries that are estimated to be the equivalent of professional athletes today, the House of Wisdom was a library established in Abbasid-era Baghdad, Iraq by Caliph al-Mansur. During this period, the Muslims showed a strong interest in assimilating the knowledge of the civilizations that had been conquered. They also excelled in fields, in particular philosophy, science. For a long period of time the personal physicians of the Abbasid Caliphs were often Assyrian Christians, among the most prominent Christian families to serve as physicians to the caliphs were the Bukhtishu dynasty. Throughout the 4th to 7th centuries, Christian scholarly work in the Greek, the House of Wisdom was founded in Baghdad in 825, modelled after the Academy of Gondishapur. It was led by Christian physician Hunayn ibn Ishaq, with the support of Byzantine medicine, many of the most important philosophical and scientific works of the ancient world were translated, including the work of Galen, Hippocrates, Plato, Aristotle, Ptolemy and Archimedes. Many scholars of the House of Wisdom were of Christian background, the use of paper spread from China into Muslim regions in the eighth century, arriving in Al-Andalus on the Iberian peninsula, present-day Spain in the 10th century. It was easier to manufacture than parchment, less likely to crack than papyrus, Islamic paper makers devised assembly-line methods of hand-copying manuscripts to turn out editions far larger than any available in Europe for centuries. It was from countries that the rest of the world learned to make paper from linen. Ibn Rushd and Ibn Sina played a role in saving the works of Aristotle, whose ideas came to dominate the non-religious thought of the Christian. Ibn Sina and other such as al-Kindi and al-Farabi combined Aristotelianism and Neoplatonism with other ideas introduced through Islam. Arabic philosophic literature was translated into Latin and Ladino, contributing to the development of modern European philosophy, during this period, non-Muslims were allowed to flourish relative to treatment of religious minorities in the Christian Byzantine Empire. The Jewish philosopher Moses Maimonides, who lived in Andalusia, is an example, in epistemology, Ibn Tufail wrote the novel Hayy ibn Yaqdhan and in response Ibn al-Nafis wrote the novel Theologus Autodidactus

Persian people
–
The Persians are an Iranian ethnic group that make up over half the population of Iran. They share a cultural system and are native speakers of the Persian language. The ancient Persians were originally a branch of the ancient Iranian population who entered modern-day Iran by the early 10th century BC. The English term Persian derives from Latin Persia, itself deriving from Greek Persís, in the Bible, it is referred to as Parás —sometimes Paras uMadai —within the books of Esther, Daniel, Ezra and Nehemya. Although Persis was originally one of the provinces of ancient Iran, varieties of this term were adopted through Greek sources, thus, in the Western world, the term Persian came to refer to all inhabitants of the country. 10th-century Iraqi historian Al-Masudi refers to Pahlavi, Dari and Azari as dialects of the Persian language, in 1333, medieval Moroccan traveler and scholar Ibn Battuta, referred to the people of Kabul as a specific sub-tribe of Persians. Lady Mary Sheil, in her observation of Iran during the Qajar era, describes Persians, Kurds and Leks to identify themselves as descendants of the ancient Persians. On March 21,1935, the king of Iran, Reza Shah Pahlavi, issued a decree asking the international community to use the term Iran. However, the term Persian is still used to designate the predominant population of the Iranian peoples living in the Iranian cultural continent. The earliest known written record attributed to the Persians is from the Black Obelisk of Shalmaneser III, the inscription mentions Parsua as a tribal chiefdom in modern-day western Iran. The ancient Persians were originally a branch of the Iranian population that, in the early 10th century BC. They were initially dominated by the Assyrians for much of the first three centuries after arriving in the region, however, they played a role in the downfall of the Neo-Assyrian Empire. The Medes, another branch of population, founded the unified empire of Media as the regions dominant cultural and political power in c.625 BC. Meanwhile, the Persian dynasty of the Achaemenids formed a state to the central Median power. In c.552 BC, the Achaemenids began a revolution which led to the conquest of the empire by Cyrus II in c.550 BC. They spread their influence to the rest of what is called the Iranian Plateau, at its greatest extent, the Achaemenid Empire stretched from parts of Eastern Europe in the west, to the Indus Valley in the east, making it the largest empire the world had yet seen. The Achaemenids developed the infrastructure to support their growing influence, including the creation of Pasargadae and its legacy and impact on the kingdom of Macedon was also notably huge, even for centuries after the withdrawal of the Persians from Europe following the Greco-Persian Wars. The empire collapsed in 330 BC following the conquests of Alexander the Great, until the Parthian era, the Iranian identity had an ethnic, linguistic, and religious value, however, it did not yet have a political import

Western world
–
The Western world or the West is a term usually referring to different nations, depending on the context, most often including at least part of Europe. There are many accepted definitions about what they all have in common, the Western world is also known as the Occident. The concept of the Western part of the earth has its roots in Greco-Roman civilization in Europe, before the Cold War era, the traditional Western viewpoint identified Western Civilization with the Western Christian countries and culture. Its political usage was changed by the antagonism during the Cold War in the mid-to-late 20th Century. The term originally had a literal geographic meaning, Western culture was influenced by many older great civilizations of the ancient Near East, such as Phoenicia, Minoan Crete, Sumer, Babylonia, and also Ancient Egypt. It originated in the Mediterranean basin and its vicinity, Greece, over time, their associated empires grew first to the east and west to include the rest of Mediterranean and Black Sea coastal areas, conquering and absorbing. Later, they expanded to the north of the Mediterranean Sea to include Western, Central, numerous times, this expansion was accompanied by Christian missionaries, who attempted to proselytize Christianity. There is debate among some as to whether Latin America is in a category of its own, specifically, Western culture may imply, a Biblical Christian cultural influence in spiritual thinking, customs and either ethic or moral traditions, around the Post-Classical Era and after. European cultural influences concerning artistic, musical, folkloric, ethic and oral traditions, the concept of Western culture is generally linked to the classical definition of the Western world. In this definition, Western culture is the set of literary, scientific, political, artistic, much of this set of traditions and knowledge is collected in the Western canon. The term has come to apply to countries whose history is marked by European immigration or settlement, such as the Americas, and Oceania. The geopolitical divisions in Europe that created a concept of East and West originated in the Roman Empire, Roman Catholic Western and Central Europe, as such, maintained a distinct identity particularly as it began to redevelop during the Renaissance. Even following the Protestant Reformation, Protestant Europe continued to see itself as more tied to Roman Catholic Europe than other parts of the civilized world. Use of the term West as a cultural and geopolitical term developed over the course of the Age of Exploration as Europe spread its culture to other parts of the world. Additionally, closer contacts between the West and Asia and other parts of the world in recent times have continued to cloud the use, herodotus considered the Persian Wars of the early 5th century BC a conflict of Europa versus Asia. The terms West and East were not used by any Greek author to describe that conflict, the Great Schism and the Fourth Crusade confirmed this deviation. The Renaissance in the West emerged partly from currents within the Roman Empire, Ancient Rome was a civilization that grew from a city-state founded on the Italian Peninsula about the 9th century BC to a massive empire straddling the Mediterranean Sea. In its 12-century existence, Roman civilization shifted from a monarchy, to a republic, nonetheless, despite its great legacy, a number of factors led to the eventual decline of the Roman Empire

Al-Biruni
–
Abū Rayḥān Muḥammad ibn Aḥmad Al-Bīrūnī, known as Al-Biruni in English, was an Iranian scholar and polymath from Khwarezm. He studied almost all fields of science and was compensated for his research, royalty and powerful members of society sought out Al-Biruni to conduct research and study in order to uncover certain findings. He lived during the Islamic Golden Age, in which scholarly thought went hand in hand with the thinking and methodology of the Islamic religion. In addition to type of influence, Al-Biruni was also influenced by other nations, such as the Greek. He was conversant in Khwarezmian, Persian, Arabic, Sanskrit and he spent a large part of his life in Ghazni in modern-day Afghanistan, capital of the Ghaznavid dynasty which was based in what is now central-eastern Afghanistan. In 1017 he traveled to the Indian subcontinent and authored Tarikh Al-Hind after exploring the Hindu faith practised in India and he was given the title founder of Indology. He was a writer on customs and creeds of various nations. He also made contributions to Earth sciences, and is regarded as the father of geodesy for his important contributions to that field and he was born in the outer district of Kath, the capital of the Afrighid dynasty of Khwarezm. The word Biruni means from the outer-district in Persian, and so became his nisba. Al-Birunis relatives also took interest in the studies of science as well and he even had ties to royalty as there are links in his family to the families of prestigious elites. In order to conduct his research, Al-Biruni used different types of methods to tackle the different fields he studied, people consider Al-Biruni to be one of the greatest scientists in history and especially of Islam because of his discoveries and methodology. He lived during the Islamic Golden Age, which promoted astronomy and he was sympathetic to the Afrighids, who were overthrown by the rival dynasty of Mamunids in 995. He left his homeland for Bukhara, then under the Samanid ruler Mansur II the son of Nuh, there he corresponded with Avicenna and there are extant exchanges of views between these two scholars. In 998, he went to the court of the Ziyarid amir of Tabaristan and he also visited the court of the Bavandid ruler Al-Marzuban. Accepting the definite demise of the Afrighids at the hands of the Mamunids and their court at Gorganj was gaining fame for its gathering of brilliant scientists. In 1017, Mahmud of Ghazni took Rey, most scholars, including al-Biruni, were taken to Ghazni, the capital of the Ghaznavid dynasty. Biruni was made court astrologer and accompanied Mahmud on his invasions into India and he was forty-four years old when he went on the journeys with Mahmud of Ghazni. Biruni became acquainted with all related to India

Sufism
–
Sufism or Taṣawwuf, which is often defined as Islamic mysticism, the inward dimension of Islam, or the phenomenon of mysticism within Islam, is a mystical trend in Islam characterized. These orders meet for sessions in meeting places known as zawiyas, khanqahs. They strive for ihsan as detailed in a hadith, Ihsan is to worship Allah as if you see Him, if you cant see Him, Rumi stated, The Sufi is hanging on to Muhammad, like Abu Bakr. Sufis regard Muhammad as al-Insān al-Kāmil, the perfect man who exemplifies the morality of God. The orders largely follow one of the four madhhabs of Sunni Islam, classical Sufis were characterized by their asceticism, especially by their attachment to dhikr, the practice of repeating the names of God, often performed after prayers. According to William Chittick, In a broad sense, Sufism can be described as the interiorization, historically, Muslims have used the Arabic word taṣawwuf to identify the practice of Sufis. In this view, it is necessary to be a Muslim to be a true Sufi. However, Islamic scholars themselves are not by any means in agreement about the meaning of the word sufi, Sufis themselves claim that Tasawwuf is an aspect of Islam similar to Sharia, inseparable from Islam and an integral part of Islamic belief and practice. Classical Sufi scholars have defined Tasawwuf as a science whose objective is the reparation of the heart and turning it away from all else, two origins of the word sufi have been suggested. Commonly, the root of the word is traced to ṣafā. Another origin is ṣūf, wool in Arabic, referring to the simple cloaks the early Muslim ascetics wore, the two were combined by the Sufi al-Rudhabari, who said, The Sufi is the one who wears wool on top of purity. Scholars generally agree that ṣūf or wool is probably the word of Sufi. This term was given to them because they wore woollen garments, the term labisal-suf meant he clad himself in wool and applied to a person who renounced the world and became an ascetic. Others have suggested that the word comes from the term ahl aṣ-ṣuffah and these men and women who sat at al-Masjid an-Nabawi are considered by some to be the first Sufis. Al-Qushayri and Ibn Khaldun both rejected all other than ṣūf on linguistic grounds. Sufi orders are based on the bayah that was given to the Prophet Muhammad by his Sahaba, by pledging allegiance to the Prophet Muhammad, the Sahaba had committed themselves to the service of God. According to Islamic belief, by pledging allegiance to Prophet Muhammad and it is through the Prophet Muhammad that Sufis aim to learn about, understand and connect with God. Such a concept may be understood by the hadith, which Sufis regard to be authentic, in which Prophet Muhammad said, I am the city of knowledge, eminent Sufis such as Ali Hujwiri refer to Ali as having a very high ranking in Tasawwuf

Iran
–
Iran, also known as Persia, officially the Islamic Republic of Iran, is a sovereign state in Western Asia. Comprising a land area of 1,648,195 km2, it is the second-largest country in the Middle East, with 82.8 million inhabitants, Iran is the worlds 17th-most-populous country. It is the country with both a Caspian Sea and an Indian Ocean coastline. The countrys central location in Eurasia and Western Asia, and its proximity to the Strait of Hormuz, Tehran is the countrys capital and largest city, as well as its leading economic and cultural center. Iran is the site of to one of the worlds oldest civilizations, the area was first unified by the Iranian Medes in 625 BC, who became the dominant cultural and political power in the region. The empire collapsed in 330 BC following the conquests of Alexander the Great, under the Sassanid Dynasty, Iran again became one of the leading powers in the world for the next four centuries. Beginning in 633 AD, Arabs conquered Iran and largely displaced the indigenous faiths of Manichaeism and Zoroastrianism by Islam, Iran became a major contributor to the Islamic Golden Age that followed, producing many influential scientists, scholars, artists, and thinkers. During the 18th century, Iran reached its greatest territorial extent since the Sassanid Empire, through the late 18th and 19th centuries, a series of conflicts with Russia led to significant territorial losses and the erosion of sovereignty. Popular unrest culminated in the Persian Constitutional Revolution of 1906, which established a monarchy and the countrys first legislative body. Following a coup instigated by the U. K. Growing dissent against foreign influence and political repression led to the 1979 Revolution, Irans rich cultural legacy is reflected in part by its 21 UNESCO World Heritage Sites, the third-largest number in Asia and 11th-largest in the world. Iran is a member of the UN, ECO, NAM, OIC. Its political system is based on the 1979 Constitution which combines elements of a democracy with a theocracy governed by Islamic jurists under the concept of a Supreme Leadership. A multicultural country comprising numerous ethnic and linguistic groups, most inhabitants are Shia Muslims, the largest ethnic groups in Iran are the Persians, Azeris, Kurds and Lurs. Historically, Iran has been referred to as Persia by the West, due mainly to the writings of Greek historians who called Iran Persis, meaning land of the Persians. As the most extensive interactions the Ancient Greeks had with any outsider was with the Persians, however, Persis was originally referred to a region settled by Persians in the west shore of Lake Urmia, in the 9th century BC. The settlement was then shifted to the end of the Zagros Mountains. In 1935, Reza Shah requested the international community to refer to the country by its native name, opposition to the name change led to the reversal of the decision, and Professor Ehsan Yarshater, editor of Encyclopædia Iranica, propagated a move to use Persia and Iran interchangeably

Ptolemy
–
Claudius Ptolemy was a Greek writer, known as a mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, beyond that, few reliable details of his life are known. His birthplace has been given as Ptolemais Hermiou in the Thebaid in a statement by the 14th-century astronomer Theodore Meliteniotes. This is a very late attestation, however, and there is no reason to suppose that he ever lived elsewhere than Alexandria. Ptolemy wrote several treatises, three of which were of importance to later Byzantine, Islamic and European science. The first is the astronomical treatise now known as the Almagest, although it was entitled the Mathematical Treatise. The second is the Geography, which is a discussion of the geographic knowledge of the Greco-Roman world. The third is the treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the Apotelesmatika but more known as the Tetrabiblos from the Greek meaning Four Books or by the Latin Quadripartitum. The name Claudius is a Roman nomen, the fact that Ptolemy bore it indicates he lived under the Roman rule of Egypt with the privileges and political rights of Roman citizenship. It would have suited custom if the first of Ptolemys family to become a citizen took the nomen from a Roman called Claudius who was responsible for granting citizenship, if, as was common, this was the emperor, citizenship would have been granted between AD41 and 68. The astronomer would also have had a praenomen, which remains unknown and it occurs once in Greek mythology, and is of Homeric form. All the kings after him, until Egypt became a Roman province in 30 BC, were also Ptolemies, abu Mashar recorded a belief that a different member of this royal line composed the book on astrology and attributed it to Ptolemy. The correct answer is not known”, Ptolemy wrote in Greek and can be shown to have utilized Babylonian astronomical data. He was a Roman citizen, but most scholars conclude that Ptolemy was ethnically Greek and he was often known in later Arabic sources as the Upper Egyptian, suggesting he may have had origins in southern Egypt. Later Arabic astronomers, geographers and physicists referred to him by his name in Arabic, Ptolemys Almagest is the only surviving comprehensive ancient treatise on astronomy. Ptolemy presented his models in convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a catalogue, which is a version of a catalogue created by Hipparchus
