Pindar, Olympian Ode 6 ant 2 (trans. Conway) (Greek lyric C5th B.C.) :
"Beside Eurotas' stream, to journey to Pitane. She, so they tell, was loved of great Poseidon, son of Kronos (Cronus), and bore the babe Euadne (Evadne), child of the crown of violet tresses, hiding the pains of maiden motherhood beneath her robe. But when the month was come of labour's term, she sent her handmaids and bade them give the child for watch and art to Eilatos' hero son at Phaisana, who ruled in Arkadia, and dwelt by Alpheios' (Alpheus') stream."
