Ixion.

    A king of Thessaly and ruler of the Lapiths, Ixion was the father by Dia of Pirithous. Rather than pay bridal-gifts, Ixion murdered his father-in-law, Eioneus, but was purified by Zeus (Jupiter). Then, ignoring the debt he owed to Zeus as well as the custom of hospitality, Ixion began to court the god’s wife, Hera (Juno). Zeus intervened, creating a phantom Hera out of a cloud (later called Nephele), to whom Ixion made love; from this union Centaurus, progenitor of the race of centaurs, was born. For his impiety, Zeus struck Ixion with a thunderbolt and ordered Hermes (Mercury) to chain him to a perpetually revolving wheel in Hades.
    Treatments of Ixion in the fine arts commonly depict him with the phantom Hera on a cloud, thrown into Hades, or bound to the wheel. He is sometimes grouped with Sisyphus, Tantalus, and Tityus as the Four Deceivers (or Disgracers, Blasphemers, Condemned).
