In Greek mythology, Medusa is viewed as such a terrifying and horrible monster that just the sight of her would turn a man to stone. She is very much a "woman in refrigerator," if you will, for her main purpose Greek stories is to hilight Perseus' victory. His story says that in order to defeat the formidable Cracken, he raised Medusa's severed head and turned the creature to rock. Of course, Latin freaks out there will probably poke holes in our story, so we'd like to protect ourselves by simply saying, hey! Snake hair looks cool! Enjoy.
