Edwin Sidney Hartland, The legend of Perseus, Volume 3… (1896)
“ Her sister appears from the river and curses him, if a man, to become a woman, if a woman, to become a man. She then carries the dead nymph back into the river, and, as it seems, there restores her to life; for immediately afterwards a magnificent black steed stands before the desolate youth (now become a girl) and declares that he is sent by the deceased maiden to bear him where his fortune blossoms. Mounted on the steed, he is borne through the air like lightning to the aid of a king’s daughter, given to a dragon who dwells in a fountain and requires a maid once a year for dinner. ”
