'Explanations of planetary motion were more difficult in ancient times than explanations of the motions of the sun and moon, because the planets reverse their motion sometimes (retrograde motion)'.

Over the course of the year, planets appear to travel generally eastward relative to the stars, but for weeks or months they appear to move backwards during these times. Since ancient people believed that Earth was at the center of the universe, this motion that occurs when Earth passes by (or is passed by) another planet in its orbit presented a significant puzzle.

Then, in order to explain the motion of the planet, the Ptolemaic Greek astronomers recommended adding circles to the elliptical orbits of the roving stars.
