Ixion was a king of the Lapiths (an ancient tribe of Thessaly) and the son of either the god Ares, Antion, or the notorious evildoer Phlegyas in Greek mythology.
Ixion was summoned to the table of the gods, but rather than being grateful, he immediately tried to seduce Zeus's wife, Hera. Zeus stopped them and then tested Ixion by trying to seduce him with a fake Hera made from a cloud. Ixion slept with her, and was later punished by being strapped to a flaming wheel that flew around the world forever. Meanwhile, the fake Hera gave birth to the Centaurs, thus the reason why Ixion is portrayed by a horse-like creature.
