Ἰτωνία, Ἰτωνίας or Ἰτωνίς) was an epithet of the Greek goddess Athena worshiped widely in Thessaly and elsewhere.
[6][7] It may be that Athena Itonia had something of the character which in her primitive worship she had at Athens, and that she was a goddess who fostered the growths of the earth and who therefore had some affinity to the Chthonic deities.
[9] From Iton her worship spread into Boeotia, where she was the chief deity of war,[8] and the country about Lake Copais.
In her temple between Pherae and Larissa were hung the shields won from the Gauls in the last victory of Greece over barbarism, although a fragment from Bacchylides indicates that Athena Itonia was not only a war goddess, but a goddess of the arts of peace, especially poetry.
[8] According to another tradition, Athena received the epithet of Itonia from Itonus, a king or priest.
