The angry goddess had changed his form into that of a deer, the animal which he and his faithful hounds had so often hunted. […] Hercules felt sure that he would win because he was so strong; and the river god felt equally sure that he would be the victor, because he could disguise himself, at any moment, and take on the form of an animal.
