Ptolemy
This system became known as the Ptolemaic system. It predicts the positions of the planets well  enough for naked-eye observations, so it seemed accurate at the time. This is described in his book Mathematical Syntaxis (widely called the Almagest), a thirteen-book mathematical treatment of the phenomena of astronomy. It contains a wide variety of information ranging from earth conceptions to sun, moon, and star movement as well as eclipses and an explanation of the length of months. The Almagest also included a star catalog containing 48 constellations, using the names we still use today.
