Fiiiiiinaly someone remembered, that Medusa was NOT originaly a lamia or naga, or whatever snake-monster comes in mind, but merely a woman cursed by jealous goddess for her hair to turn into snakes! She wasn't even a magic-user, in fact, people didn't turn into literal statues, they were just paralyzed by fear, as back in the days people were far less used to monsters than we are know, when monsters are practicly everywhere in the media.
