daughter, Hebe, and had two sons with her, Alexiares and Anicetus. When Hades requested to marry Zeus's daughter, Persephone, Zeus approved and advised Hades to abduct Persephone, as her mother Demeter wouldn't allow her to marry Hades. Zeus fell in love with Semele, the daughter of Cadmus and Harmonia, and started an affair with her. Hera discovered his affair when Semele later became pregnant, and persuaded Semele to sleep with Zeus in his true form. When Zeus showed his true form to Semele, his lightning and thunderbolts burned her to death. Zeus saved the fetus by stitching it into his thigh, and the fetus would be born as Dionysus. In the Orphic "Rhapsodic Theogony" (first century BC/AD), Zeus wanted to marry his mother Rhea. After Rhea refused to marry him, Zeus turned into a snake and raped her. Rhea became pregnant and gave birth to Persephone. Zeus in the form of a snake would mate with his daughter Persephone, which resulted in the birth of Dionysus.

However, at the request of Apollo's mother, Leto, Zeus instead ordered Apollo to serve as a slave to King Admetus of Pherae for a year. According to Diodorus Siculus, Zeus killed Asclepius because of complains from Hades, who was worried that the number of people in the underworld was diminishing because of Asclepius's resurrections. The winged horse Pegasus carried the thunderbolts of Zeus. Zeus took pity on Ixion, a man who was guilty of murdering his father-in-law, by purifying him and bringing him to Olympus. However, Ixion started to lust after Hera. Hera complained about this to her husband, and Zeus decided to test Ixion. Zeus fashioned a cloud that resembles Hera (Nephele) and laid the
