Why was Ptolemy's Earth-centered system of epicycles taught throughout Europe for over a thousand years?
Because plain circular orbits could not explain the way the planets move. The philosophers said that the circle was the perfect curve, and Ptolemy's model used circles and epicycles. An epicycle is a small circle whose centre travels round a larger circle, and the planet then travels round the epicycle. Extra epicycles were added to account for things like the eccentric orbits (which are now recognised as elliptical), and the inclination of the orbits. However Ptolemy's model represented the movements of the planets pretty accurately which is why no-one thought to challenge it for 1400 years. Ptolemy's model was also in use in planetariums until modern times, when computer driven planetariums took over. In Ptolemy's model both Venus and Mars have very large epicycles, which we now understand are there to account for the Earth's movement round the Sun.
What was ptolemys biggest discovery?
