Like the Sun and the Moon, the planets all move near the ecliptic, never being more than a ... After a millenium, however, the Ptolemaic model increasingly deviated from the planets' observed motions. Other astronomers tried to correct it by adding additional levels of epicycles, but the result was exceedingly complex.

Earlier theories of planetary motion, such as the geocentric Ptolemaic system and the heliocentric Copernican system, had allowed only perfect circles as orbits and were therefore compelled to combine many circular motions to reproduce the variations in the planets' motions.
