 The most detailed account of the Gigantomachy is that of the (first century 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 and 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.
