I should also add that Gorgon was originally a monster created by Gaia to fight in the war between Gods and Titans which was killed by Athena. After the 3 sisters were villainized its name was somehow applied to them.
Sisters Euryale, Medusa & Stheno were originally beloved earth Goddesses not considered ugly at all. Shared with the Furies, snakes are earthly creatures symbolizing sacredness, immortality & wisdom. They turned enemies into stone - i.e. earth. Medusa's hands were bronze; metal comes from the earth. They were also related to the Babylonian Goddess Lamashtu. It was patriarchal Greek culture that demonized
them & reveled in violence against women.
