The House of Ptolemy web site concentrates on the Ptolemies and their world, from 331 - 30 BCE. However, since the histories of Greek rule and subsequent Roman rule overlap (and do so again later with Byzantine rule) this site includes Roman rule in Egypt, and the Byzantine rule that followed. During this almost 1000 years the dominant culture ['Hellenistic'] started as a Greek core with added native Egyptian and other foreign elements. These elements were both blended and kept distinctly separate, sometimes overlying the Greek core incompletely so that today scholars can focus on the Greek facets, the native Egyptian facets, the other outside influences, or all of these together when they discuss

Extractions: In his Dialogue Concerning the Two Chief World Systems, Ptolemaic and Copernican of 1632, Galileo attacked the world system based on the cosmology of Aristotle (384-322 BCE) and the technical astronomy of Ptolemy (ca. 150 CE). In his books On the Heavens, and Physics, The heavens, on the other hand, were made up of an entirely different substance, the aether or quintessence (fifth element), an immutable substance. Heavenly bodies were part of spherical shells of aether. These spherical shells fit tightly around each other, without any spaces between them, in the following order: Moon, Mercury, Venus, Sun, Mars, Jupiter, Saturn, fixed stars. Each spherical shell (hereafter, simply, sphere) had its particular rotation, that accounted for the motion of the heavenly body contained in it. Outside the sphere of the fixed stars, there was the prime mover (himself unmoved), who imparted motion from the outside inward. All motions in the cosmos came ultimately from this prime mover. The natural motions of heavenly bodies and their spheres was perfectly circular, that is, circular and neither speeding up nor slowing down. It is to be noted about this universe that everything had its natural place, a privileged location for bodies with a particular makeup, and that the laws of nature were not the same in the heavenly and the earthly regions. Further, there were no empty places or vacua anywhere. Finally, it was finite: beyond the sphere of the fixed stars and the prime mover, there was nothing, not even space. The cosmos encompassed all existence.

Ptolemy - Creator Of The Ptolemaic System - Earth Centered Universe
Discover ptolemy, astronomer, mathematician and geographer who lived in Alexandria, Egypt. We know very little more of his life. He classified the Greek geocentric view of the universe, and calculated the apparent motions of the planets.
http://space.about.com/library/weekly/aa103102a.htm

Extractions: Ptolemy (aka Claudius Ptolemaeus, Ptolomaeus, Klaudios Ptolemaios, Ptolemeus) lived in Alexandria, Egypt. We know very little of Ptolemy's life, including his birth and death dates. Various sources report different years, however, the first observation made by Ptolemy which we can date exactly was on 26 March 127 while the last was on 2 February 141. Some experts believe his life spanned the years 87 150. We get a few clues about him from his name, Claudius Ptolemy, which is a mixture of the Greek Egyptian 'Ptolemy' and the Roman 'Claudius'. This seems to indicate that he was descended from a Greek family living in Egypt and that he was also a citizen of Rome. This could only have happened as a result of a Roman emperor rewarding one of Ptolemy's ancestors with this favor.

Extractions: Ptolemy's world map Ptolemy's World Map, c. 150 AD. Ptolemy's world map, republished in 1482. Ptolemy (c.100-168) the Greek astronomer and the author of works on physics, mathematics, optics and geography, produced the data for creating a world map in about 150 AD. Unfortunately, none of his maps survived and his work was lost to the West until the Renaissance. Scholars in the 15th century recreated Ptolemy's map using the instructions in his work Geography, which explain how to project a sphere onto a flat piece of paper using a system of gridlines - longitude and latitude. Ptolemy's map consists of the world known to him; he does not speculate on the unknown, and as he worked in Alexandria the map is most detailed round the Mediterranean. There are only three continents: Europe, Asia and Africa. The two red lines are the Tropics of Cancer and Capricorn; the sea is light brown, the rivers are in blue and the mountains in dark brown.

CATHOLIC ENCYCLOPEDIA: Ptolemy The Gnostic
(Catholic Encyclopedia)
http://www.newadvent.org/cathen/12553c.htm

Extractions: Home Encyclopedia Summa Fathers ... P > Ptolemy the Gnostic A B C D ... Z Supreme God , nor to the devil ; nor does it proceed from one law-giver. A part of it is the work of an inferior god; the second part is due to Moses, and the third to the elders of the Jewish people. Three different sections are to be distinguished even in the part ascribed to the inferior god: It includes such precepts as circumcision, fasting, and was raised by the Saviour from a sensible to a spiritual plane. The god who is the author of the law, in so far as it is not the product of human effort, is the demiurge who occupies a middle position between the Supreme God and the devil . He is the creator of the universe, is neither perfect, nor the author of evil, but ought to be called just. In his interpretation of the universe, Ptolemy resorted to a fantastic system of eons. Thirty of these, as he believes, rule the higher world, the pleroma. This system becomes the basis of a wild exegesis which discovers in the prologue of St. John's Gospel the first Ogdoad. (See GNOSTICISM.)

http://www-gap.dcs.st-and.ac.uk/~history/Mathematicians/Ptolemy.html

Extractions: One of the most influential Greek astronomers and geographers of his time, Ptolemy propounded the geocentric theory in a form that prevailed for 1400 years. However, of all the ancient Greek mathematicians, it is fair to say that his work has generated more discussion and argument than any other. We shall discuss the arguments below for, depending on which are correct, they portray Ptolemy in very different lights. The arguments of some historians show that Ptolemy was a mathematician of the very top rank, arguments of others show that he was no more than a superb expositor, but far worse, some even claim that he committed a crime against his fellow scientists by betraying the ethics and integrity of his profession. We know very little of Ptolemy's life. He made astronomical observations from Alexandria in Egypt during the years AD 127-41. In fact the first observation which we can date exactly was made by Ptolemy on 26 March 127 while the last was made on 2 February 141. It was claimed by Theodore Meliteniotes in around 1360 that Ptolemy was born in Hermiou (which is in Upper Egypt rather than Lower Egypt where Alexandria is situated) but since this claim first appears more than one thousand years after Ptolemy lived, it must be treated as relatively unlikely to be true. In fact there is no evidence that Ptolemy was ever anywhere other than Alexandria.

Extractions: Ptolemy, who gave Greek astronomy its final form in the second century A.D., did the sameand morefor geography and cartography. His massive work on the subject, which summed up and criticized the work of earlier writers, offered instruction in laying out maps by three different methods of projection, provided coordinates for some eight thousand places, and treated such basic concepts as geographical latitude and longitude. In Byzantium, in the thirteenth century, Ptolemic maps were reconstructed and attached to Greek manuscripts of the text. And in the fifteenth century, a Latin translation of this text, with maps, proved a sensation in the world of the book. A best seller both in the age of luxurious manuscripts and in that of print, Ptolemy's "Geography" became immensely influential. Columbus one of its many readersfound inspiration in Ptolemy's exaggerated value for the size of Asia for his own fateful journey to the west. Ptolemy, Handy Tables In Greek, Ninth century

Extractions: Ptolemy (aka Claudius Ptolemaeus, Ptolomaeus, Klaudios Ptolemaios, Ptolemeus) lived in Alexandria (in Egypt) from approx. 87 -150 AD. Very little is known about his personal life (the image above is probably purely the artist's imagination) He was an astronomer, mathematician and geographer. He codified the Greek geocentric view of the universe, and rationalized the apparent motions of the planets as they were known in his time. Ptolemy synthesized and extended Hipparchus's system of epicycles and eccentric circles to explain his geocentric theory of the solar system. Ptolemy's system involved at least 80 epicycles to explain the motions of the Sun, the Moon, and the five planets known in his time. He believed the planets and sun to orbit the Earth in the order Mercury, Venus, Sun, Mars, Jupiter, Saturn . This system became known as the Ptolemaic system. It predicts the positions of the planets accurately enough for naked-eye observations This is described in the book Mathematical Syntaxis (widely called the Almagest ), a thirteen book mathematical treatment of the phenomena of astronomy. It contains a myriad of information ranging from earth conceptions to sun, moon, and star movement as well as eclipses and a breakdown on the length of months. The Almagest also included a star catalog containing 48 constellations, using the names we still use today.
