Claudius Ptolemy and the Geography
Claudius Ptolemy
A representation of Ptolemy from
the Blaeu Atlas Maior (1662)
Ptolemy was born in Upper Egypt and lived in Alexandria, ca. A.D. 90-168. He was a polymath who wrote treatises on astronomy, mathematics, physics, optics, harmonics, chronology, and geography. A number of his works contain material relevant to map making. For example: Analemma deals with the theory of the gnomon and orthographic projection; Planisphaerium examines stereographic projection; Tetrabiblos, a treatise on astrology, has references to geography; Mathematical Syntaxis (called Almagest) teaches how to draw a celestial globe; and Geography shows how to draw a map of the inhabited world on a globe or on a plane surface. Ptolemy’s greatest influence on cartography was through translations of Almagest and Geography.

The Geography
The Geography represents the culmination and synthesis of the scientific tradition in Greek cartography; it consists of eight books, and anywhere from 26 to 64 maps. The Geography has been cited in the literature from as early as the sixth century and was widely used by Muslim scholars and navigators. Whilst the work had no real impact on Western European cultur

Claudius Ptolemy (; Ancient Greek: Πτολεμαῖος, Ptolemaios; Latin: Claudius Ptolemaeus; c. 100 – 160s/170s AD)[1] was an Alexandrian mathematician, astronomer, astrologer, geographer, and music theorist[2] who wrote about a dozen scientific treatises, three of which were important to later Byzantine, Islamic, and Western European science. The first was his astronomical treatise now known as the Almagest, originally entitled Mathematical Treatise (Greek: Μαθηματικὴ Σύνταξις, Mathēmatikḗ Syntaxis). The second is the Geography, which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristoteliannatural philosophy of his day. This is sometimes known as the Apotelesmatika (Greek: Αποτελεσματικά, lit. 'On the Effects') but more commonly known as the Tetrábiblos, from the Koine Greek meaning "Four Books", or by its Latin equivalent Quadripartite. The Catholic Church promoted his work, which included the only mathematically sound geocentric model of the Solar System, and unlike most Greek mathem Ptolemy
