"Ixion is the father of all centaurs except for Chiron. Ixion was king of the Lapiths in Thessaly, but not a very honourable king. For example, he married a woman named Dia, daughter of Eioneus....but decided not to pay the previously agreed upon price for his new bride. Eioneus held, for security on the debt, some horses that belonged to Ixion. Ixion told Eioneus that if he would bring the horses to Thessaly, Eioneus would be paid what he was due...but once there, killed Eioneus. Zeus decided to purify Ixion and he went to Olympus for the ritual. But while there, Ixion committed an even worse sin...he tried to seduce Zeus' wife, Hera! She told her husband, who then decided to verify Ixion's guilt with a test: he took a cloud, shaped it like Hera, and set it where Ixion would find it. Well, Ixion took the bait, and slept with the fake Hera. When Ixion came down to earth, he bragged to other mortals about sleeping with the queen of the gods. In punishment, Zeus bound Ixion to a winged or flaming spinning wheel in the Underworld upon which Ixion was forced to continuously repent: 'show gratitude to your benefactor'."
