Daughter of Ocean, and one of the attendants of Artemis in Greece's western woodlands. As she returned one day from hunting, she sat near the the Alpheos, and bathed in the stream. The god of the river was enamored of her and he pursued her over the mountains and all the country, when she, sinking under fatigue, implored Artemis, who changed her into a spring, and so she slipped away. The river Alpheos followed her also under the sea, and rose also on the Sicilian shore at Ortygia: so that, whatever is thrown into the Alpheos in Elis, rises again, after some time, in the fountain Arethusa near Syracuse.
