CYANE
a Sicilian nymph and playmate of Proserpina, who was changed through grief at the loss of Proserpina into a well. The Syracusans celebrated an annual festival on that spot, which Heracles was said to have instituted and at which a bull was sunk into the well as a sacrifice. A daughter of Liparus was likewise called Cyane.
