What racy secrets the Gods try and keep from us. When DEMETER tried to flee POSEIDON’s unwelcome advances by turning into a mare, she hadn’t reckoned on his having invented horse racing. There was no chance of escape and before long DEMETER was with horse and daughter.

However she doesn’t easily fit into the usual squadron of NYMPHS as she became something of an Eleusinian mystery.
