Claudius Ptolemy lived in Alexandria, inEgypt, in the middle of the second century CE. He was descended from an Egyptian familyand associated with the renowned library situated in the city. He is celebrated for hisgreat work of astronomy, known today as the Almagest. In fact, the very title istestament to its status and its tortuous history. Almagest is a transliterationof the name given to the work when it was rendered into Arabic in the early middle ages.The Islamic scholars, aware of what they possessed, called it The greatest work,and the name stuck when it was later retranslated into Latin. Ptolemy himself, however,had used the more modest Greek title, Syntaxis - Treatise (or System)of mathematics.

The Almagest provided what was asfar as we know the first complete guide to calculating the planetary motions. To achievethis, Ptolemy adopted a number of conceptually simple but mathematically complexprocedures. He reasoned that a planet must move on a combination of circular motions,which must be uniform - but that in

Ptolemy is one of the remarkable mathematicians of all time. His entire life revolves around the works he did mainly in mathematics, astronomy, geography, and astrology. However, he also contributed to optics and music to some extent. Almagest – his masterpiece book on planetary laws had been studied for many centuries by the scientists of high standing. The geocentric model of our Solar System was introduced by him.

Biography – Life Span

Claudius Ptolemy was born in Alexandria, Egypt in 100 AD. His family background and childhood are not very clear in history, except his name which some scholars claim was often found in the rich class of Macedonia. His overall history is mostly found in his contributions to science.

In the field of mathematics, he had a good command of trigonometry. He used trigonometry as a tool to learn the motion of visible objects in the sky. The importance of his astronomical work was first recognized by Arab scientists. In his astronomical work, the most invaluable masterwork was his book the Almagest. The book contains calculations that helped him compu

This article is about Ptolemy (disambiguation). For other uses, see Ptolemy (disambiguation).

Claudius Ptolemy ( Greek: Πτολεμαῖος, Ptolemaios; Latin: Claudius Ptolemaeus; c. 100 – c. 170 AD) was an Alexandrian mathematician, astronomer, astrologer, and geographer.

Ptolemy's writings never ceased to be copied or commented upon, both in Late Antiquity and in the Middle Ages. However, it is likely that only a few truly mastered the mathematics necessary to understand his works.

Biography

Ptolemy lived in or around the city of Alexandria, in the Roman province of Egypt under Roman rule, had a Latin name, which is generally taken to imply he was also a Roman citizen, cited Greek philosophers, and used Babylonian observations and Babylonian lunar theory.

The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou (Πτολεμαΐς Ἑρμείου) in the Thebaid (Θηβᾱΐς). However, there is no evidence to support it.

Claudius Ptolemy died in Alexandria c. 168.
