Pliny, quoting Euanthes, says (Hist. Nat. viii. 22) that a man of the Antaeus family was selected by lot and brought to a lake in Arcadia, where he hung his clothing on an ash tree and swam across. This resulted in his being transformed into a wolf, and he wandered in this shape nine years. Then, if he had attacked no human being, he was at liberty to swim back and resume his former shape.
Ovid IX, 184.
