 The "Bibliotheca" provides a good summary of the Gorgon myth.Much later stories claim that each of three Gorgon sisters, Stheno, Euryale, and Medusa, had snakes for hair, and that they had the power to turn anyone who looked at them to stone.According to Ovid, a Roman poet writing in 8 AD, who was noted for accuracy regarding the Greek myths, Medusa alone had serpents in her hair, and he explained that this was due to Athena (Roman Minerva) cursing her.
