The names of the species of the nymphs varied according to their natural abode. The Aulonaid (from the classical Greek αύλών; valley, ravine) was a nymph who could be found in the mountain pastures and vales, often in the company of Pan, the god of nature. Eurydice, for whom Orpheus traveled into dark Hades, was an Auloniad, and it is in the valley of the Thessalian river Peneius where she met her death at the hands of Aristaeus, son of the god Apollo and the nymph Cyrene, whose desire to ravage her led her to tread on a poisonous serpent.
