“When Medusa was killed, her powers were plundered. She was pregnant with her son Chrysaor and the winged horse Pegasus who were born from her severed neck. Pegasus was immediately captured and made to bring Zeus Medusa's roar and the flash of her eyes, which he used as his thunder and lightning. In book three of the Bibliotheca (3.10.3) Apollodorus describes how Athena drains the blood from Medusa's veins and gives it to Asclepius, Greek god of medicine and healing. The blood from her left side is deadly poisonous, while the blood from her right side brings life. Asclepius's powers to cure and raise the dead were thereby stolen from Medusa.” Medusa MythologyAsclepius Book:Re-visioning Medusa: from Monster to Divine Wisdom Source: Re-visioning Medusa: from Monster to Divine Wisdom
