The Dictionary of Mythology by J. A. Coleman (Arcturus Publishing, 2007) describes a gorgon as:
3 snake-haired, winged female monsters
A glance from these monsters [...] could turn a man to stone. Their names were Euryale, Medusa, and Stheno and only Medusa was mortal.
They lived in Cisthene and were depicted as having snakes for hair, tusks like a boar, hands of brass and the hindquarters of a mare.
Of course, over time that was weeded down to being snakes for hair and eyes that would petrify you where you stood. Needless to say, I've never read a paranormal romance containing one of these creatures, though it would be interesting, don't you think? Gorgons appear in Library by Apollodorus and in Metamorphoses by Ovid.
Cherish D'Angelo will kick off October as she talks about her new release! Hope to see you there.
