Hera, the queen of the Olympian gods of Greece, was the mother of the four gods: Hephaestus, Ares, Eilithyia and Hebe. In some traditions, she is also the mother of Eris, Ares' twin sister. Enyo is another possible child, but it is likely Enyo is another name for Eris.
Zeus, Hera's husband, may not have fathered all her children. Hera gave birth to Hephaestus by herself, though in some tales she was so disappointed at his lameness that she cast him from Olympus. In other stories, Zeus cast Hephaestus out because he interfered with Zeus' sexual advances toward the unwilling Hera. According to mythologist Arthur Bernard Clark, Hebe may have been fathered by a head of lettuce and Ares by a special flower, though these origins are disputed by other scholars.
