The name "Ionian" comes from the Greek word ''
. Its etymology is unknown. Ancient Greek writers, especially Aeschylus, linked it to the myth of Io. In ancient Greek the adjective Ionios
() was used as an epithet for the sea because Io swam across it. According to the Oxford Classical Dictionary'', the name may derive from
Ionians who sailed to the west, however the word for Ionians is spelled with an omega ( Ἴωνες) rather than an omicron as in the word for the Ionian Sea. There were also narratives about other
eponymic legendary figures: according to one version, Ionius, son of Adrias (eponymic for the
Adriatic Sea); according to another, Ionius, son of Dyrrhachus. When Dyrrhachus was attacked by his own brothers,
Heracles, who was passing through the area, came to his aid, but in the fight the hero killed his ally's son by mistake. The body was cast into the water, which thereafter was called the Ionian Sea. ==Geography==
