Scylla had been a beautiful maiden, but because of jealousy was turned into a monster by a jealous goddess Circe who loved the merman Glaucus. Glaucus however preferred beautiful Scylla. Circe was punished by Zeus by being banished to a remote island where she lived surrounded by wild animals, and where she transformed Odysseus' men into swine. Odysseus stayed on Circe'ss island, and also passed the dangerous monster Scylla, who grabbed and killed one or more of his men.
