Ixion

The first murderer of a family member, who killed his father-in-law when he didn't give him his dowry. Zeus gave him penance, and in return Ixion tried to seduce Hera. Zeus then sent a cloud image, Nefele, which Ixion had his way with.For his ungratefulness Ixion was tied to a rotating wheel of fire, forever turning in the air.
