Usually the story is that Medusa was an Athena priestess, who once made love to Poseidon in Athena's temple. In revenge Athena turned Medusa into something as ugly as possible.
Another Answer:
Because she was making love in a temple that belonged to Athena and in rage Athena turned Medusa's hair into snakes, or Medusa bragged about her hair and Hera, out of jealousy, turned her hair into snakes. Whatever makes sense to you.
Yet Another Answer:
Medusa once informed Athena that Snakes were more Fair(more beautiful) than Athena herself in order to spite her. In a fit of rage Athena damned Medusa to become that which she held so high.
Medusa was once human. However she was raped by Poseidon in the temple of Athena. Athena solely punished Medusa for her beauty by turning her into the hideous creature she was famous for. The gods were capable of doing such cruel acts to mortals and think they were rightly justified. We might not agree though.
why does medusa have snake hair well the reasen was back in the day of the olympian gods posideon and Athena were married and posideon had a secret a ffair with a mortal named meda.one night posideon and meda went to the temple of Athena and had sex by taking off the brawl of medusa and all of her other clothes and touchin everything and then Athena walked in she saw so she cursed meda with the hair of a sanke and meda renamed herself after the name of the snake medusa and the snake had a power to send invisible concrete into your body and freeze you if you looked at the eyes of medusa.
Medusa was a priestess of Athena. Later she was seduced by posideon and when she ran from him, he raped her in athena's temple. Medusa prayed to Athena for protection, but Athena didn't come. Later Athena appeared to medusa and told her that since medusa was such a flirt herself, that she deserved it and Athena would protect all mortal men from her by making her deadly to men. The other part of her curse was that she could not harm women. Medusa was sent into exile.
