Itonus
In Greek mythology, Itonus was the son of Amphictyon. He was married to Melanippe, a nymph, and had a son Boeotus and two daughters, Chromia and Iodame.
He founded a sanctuary of Athena, where his daughter Iodame served as priestess. Itonis and Itonia, surnames of Athena, were believed to have been derived from his name.
Itonus was also the name of the son of another Boeotus (the son of Poseidon). He was the father of Electryon, Hippalcimus, Archilycus (Areilycus) and Alegenor; his grandsons were the Trojan War heroes Leitus, Peneleos, Prothoenor, Arcesilaus and Clonius.
