Answer: The myth of Perseus and Medusa.
Explanation:
The Medusa is one of three Gorgons, the freak daughters of the sea god Fork and his wife, Keta. She was a beautiful girl at first, and her hair stood out in particular. However, when she dishonoured Poseidon in the Temple of Athena, Athena punished, and instead of the hair on her head, there were snakes. Any mortal who would see her afterwards would flinch with fear.
The Medusa was killed by Perseus, equipped with winged sandals, a magic curved sword, a magic helmet and a shield that had a reflection of a mirror. He cut off her head with a sword, and a giant Hrisaor and a winged horse, Pegasus, emerged from her body. From the blood dripping from her head, all the poisonous snakes known to this day flowed out. He donated her head to Athena, and she fastened it to her shield. Zeus himself allegedly carried her head on his guard, which is why all the Greek heroes had Medusa's head on their shields.
