How did persueus kill Medusa?
Persueus cut her head off.
Athens did not kill Medusa, Athens is a city in Greece. Medusa was killed by the hero 'Perseus' with the help of Athena and his brother Hermes. He killed Medusa by using a shield to see her reflection. This was because staring at Medusa would lead to being paralyzed in stone. He cut her head off and proceeded to use her as a weapon.
Athena was the one that cursed Medusa. She caught Medusa, then a beautiful sea nymph, meeting with Poseidon in one of her temples. Athena was so mad that she cursed Medusa with snake hair and eyes that will turn people into stone. This is probably why Athena helped Perseus kill Medusa and then placed Medusa's head on her shield.
There was no purpose for either Medusa or Perseus. Medusa was the only mortal Gordon (dreadful female creatures) whose eyes turned people to stone. That is all there was to her. She probably liked to just mind her own business. Perseus was sent to kill her and fetch her head by a king. The king wanted to get rid of him and thought he would be killed by Medusa. Perseus managed to kill her thanks…
