Numerous other sources mention Typhon as being the offspring of Gaia, or simply "earth-born", with no mention of Tartarus. However, according to the "Homeric Hymn to Apollo" (6th century BC), Typhon was the child of Hera alone. Hera, angry at Zeus for having given birth to Athena by himself, prayed to Gaia, Uranus, and the Titans, to give her a son stronger than Zeus, then slapped the ground and became pregnant. Hera gave the infant Typhon to the serpent Python to raise, and Typhon grew up to become a great bane to mortals.
