Geocentric model of Greek astronomer and geographer Ptolemy, who flourished in 2nd century at Alexandria, for the universe dominated cosmological theory until the Renaissance.

Ptolemy compiled Almagest , a comprehensive treatise on astronomy, geography, and mathematics, about 150.

Claudius Ptolemy (circa 90 鈥� circa 168), a Roman citizen of Egypt, wrote. As a poet, he composed a single epigram in the Anthology. He lived in Egypt under Roman rule. Theodore Meliteniotes proposed possibly correct but late and unsupported birthplace in the town of Ptolemais Hermiou in the Thebaid circa 1360.

Quotes by Ptolemy (?)

“I know that I am mortal by nature, and ephemeral; but when I trace at my pleasure the windings to and fro of the heavenly bodies I no longer touch the earth with my feet: I stand in the presence of Zeus himself and take my fill of ambrosia”
― Ptolemy, Ptolemy's Almagest

“Mortal as I am, I know that I am born for a day. But when I follow at my pleasure the serried multitude of the stars in their circular course, my feet no longer touch the earth.”

“From all this we concluded that the first two divisions of theoretical philosophy should
rather be called guesswork than knowledge, theology because of its completely invisible
and ungraspable nature, physics because of the unstable and unclear nature of the matter;
hence there is no hope that philosophers will ever be agreed about them; and that only
mathematics can provide sure and unshakable knowledge to its devotees, provided one
approaches it rigorously. For its kind of proof proceeds by indisputable methods, namely
arithmetic and geometry (tr. Toomer, p. 6).”
― Ptolemy, The Almagest: Introduction to the Mathematics of the Heavens
