moon was passing by closer to the earth, its motion would seem faster and it would look larger (because it was closer); otherwise, it would appear slower and smaller. The notion of an epicycle was to say that there was a circle of rotation around the earth, but to reject the idea that the rotating body itself would be placed on that circle. Instead, a smaller rotating circle would be placed on the larger circle rotating around the earth, and this smaller circle is called a deferent. The body itself rotates around the circle of the deferent, meanwhile the deferent as a whole would be rotating around the earth. This would also enable an observer from the earth to observe an irregular motion on the part of the astral body.

model of the solar system was proposed, and, for the first time, explanations for planetary observations were posited in the form of geometric theories. The two-sphere model posits that heaven and earth are a pair of concentric spheres. That is to say, that both heaven and earth are conceived of as a sphere which have the same center. In this way, they resemble the structure of an (conceptually spherical) egg, with an outer sphere (the heaven) encompassing an inner sphere (the earth). The outer, celestial sphere contains the fixed stars as well as the sun, moon, and planets moving along its surface. The inner terrestrial sphere is fixed in the center. Out of this arises the concept of a "

introduced to the model, such as the planets, it became more complex. The models for Jupiter, Saturn, and Mars included the center of the circle, the equant point, the epicycle, and an observer from earth to give perspective. The discovery of this model was that the center of the Mercury and Venus epicycles must always be colinear with the Sun. This assures of bounded elongation. Bounded elongation is the angular distance of celestial bodies from the center of the universe. Ptolemy's model of the

Though Proclus criticized some elements of the Almagest, such as its suggestion of the existence of epicycles, he and future Neoplatonists believed astronomy was essential to theology and continued to read Ptolemy's works. Students and successors of Proclus to continue working in the tradition of the Almagest included 6638: 1025: 3728: 752:; no indications of such knowledge of Babylonian astronomy exists for previous Greek authors. It is not known how he had access to this information and it is likely that knowledge of Babylonian astronomy among the successors of Hipparchus in later eras, such as Ptolemy, relied on Hipparchus for their information of it. Hipparchus' observations allowed him to discover that the 214: 448:(270 BC), is the primary source for his work on this subject. The seventh and eighth books of the Almagest would constitute a star catalogue of the names, positions, and magnitudes of over a thousand stars that Ptolemy placed into the traditional classification of 48 constellations. The most important of these were the twelve constellations that defined the 503:, the idea that the Earth was at the center of the solar system (or even cosmos) and that the other heavenly bodies, including the sun, moon, and the planets revolved around it, was dominant in ancient Greece and ancient cosmographical systems more generally. However, various alternatives appeared at one time or another. For example, the 707:
