The most detailed account of the Gigantomachy is that of the (first or second-century AD) mythographer Apollodorus. None of the early sources give any reasons for the war. Scholia to the "Iliad" mention the rape of Hera by the Giant Eurymedon, while according to scholia to Pindar's "Isthmian" 6, it was the theft of the cattle of Helios by the Giant Alcyoneus that started the war. Apollodorus, who also mentions the theft of Helios' cattle by Alcyoneus, suggests a mother's revenge as the motive for the war, saying that Gaia bore the Giants because of her anger over the Titans (who had been vanquished and imprisoned by the Olympians). Seemingly, as soon as the Giants are born they begin hurling "rocks and burning oaks at the sky".
