In Greek mythology, Arethusa (; Greek, Ancient (to 1453);: Ἀρέθουσα|Aréthousa) is a minor figure from Ithaca who is transformed into a fountain bearing her name. Her story survives in scholia on Homer's epic poem the Odyssey.
Arethusa was a woman from the island of Ithaca; other than a son, no other family or lineage of hers is preserved. According to an anonymous scholiast on Homer, Arethusa had a son named Corax (meaning "raven") who was a hunter.[1] One day while hunting a hare, Corax accidentally fell off a cliff and died. Out of grief for losing her son, the inconsolable Arethusa was transformed into a fountain bearing her name on the spot Corax died, while the rock there took the name of the dead son thereafter.[2] [3]
In the Odyssey, after returning home following a long ten-year long journey, the disguised king Odysseus finds his slave Eumaeus tending the swine which graze next to the rock of Corax and the fountain of Arethusa.[4]
Arethusa was a common name for springs in antiquity; today a spring with the same name in Pera Pigadi on Ithaca can be potentially identified with the mythological one, but much of this is speculative.[5]
