The epicycle theories were based on a false belief that Earth was at the center and the sun, moon, planets and the stars orbited around Earth. Because the foundation was false it led to ever more complicated versions of epicycle theories as an attempt to try to fit observed reality into a false theoretical foundation.
"According to one school of thought in the history of astronomy, minor imperfections in the original Ptolemaic system were discovered through observations accumulated over time. It was mistakenly believed that more levels of epicycles (circles within circles) were added to the models to match more accurately the observed planetary motions." --
