Scylla was a nymph, daughter of Phorcys. She was loved by Glaucus, a sea god. Scylla knew that he loved her, but she did not love him. She fled from him onto a land were he could not follow her. Glaucus turned to the enchantress Circe in anguish. He explained to her his story and how much he loved Scylla, and he wanted a love potion that would make her love him. As Circe listened to the sea god, she became enchanted by his charm. She soon fell in love with him, but Glaucus rejected her, knowing that Scylla was the only person for him. Circe got very mad at Scylla, but not at Glaucus.
Circe prepared a small vial of a very powerful poison, and poured it into the pond where Scylla bathed. As soon as the nymph touched the still water, her body transformed into a scary beast with 12 feet and 6 heads. Each of her six heads had three rows of teeth, and, from her waist down, she was made up of ugly monsters, like dogs, whose barks never ceased.
Unable to move, Scylla stood next to Charybdis in utter distress. She was envious to everything she saw, and would destroy anything that came within her reach. Scylla became a horror among sailors. Whenever a ship passed, each of her heads would swallow one of the crew members.
