This belief gave way to the ancient Greek theory of a geocentric or Ptolemaic model of the universe. "Geocentric" refers to the belief that the Earth is the center of the universe. clip from "The Universe -- Infinite Frontier" about astronomer/geographer/mathematician Ptolemy The geocentric model was the predominant description of the cosmos in many ancient civilizations, such as those of Aristotle in Classical Greece and Ptolemy in Roman Egypt. Two observations supported the idea that Earth was the center of the Universe: First, from anywhere on Earth, the Sun appears to revolve around Earth once per day. In his treatise Almagest, which was released in the 2nd century CE, Ptolemy unveiled his concept for a geocentric universe, which would remain the accepted view for the next 1500 years.

Explanation: Ptolomy's model of the solar system was geocentric, where the sun, moon, planets, and stars all orbit the earth in perfectly circular orbits. The problem with perfectly circular orbit around the Earth is that they do not explain the occasional backward motion, or retrograde motion, of the planets. The geocentric model of the universe looked like the left figure shown, with all celestial objects orbiting Earth in perfect circles. The brightest planets are visible to the naked eye, and they move through the background of the stars from one night to the next.

GEOCENTRIC MODEL 1. Earth is at the center of the universe. Ptolemaic System proposed by Claudius Ptolemy. Claudius Ptolemy accepted Aristotle's idea that the Sun, planets, and moon revolve around the Earth, a geocentric view. He developed his mode through observation and mathematical details.
