What's interesting though is that the original Furies were all merciless females, Furiae being the Latin name for the three daughters of the Greek god Gaia.

[53] In Apuleius's Metamorphoses women change their shapes by rubbing themselves with ointment, there are lamiae noxiis (horrible witches), taeterrimaeque Furiae (hideous Furies), [54] cantatrices anus (old enchantresses), [55] Thessalian witches who bite the face of a corpse, [56] and have the supernatural power to bring down the sky, raise the spirits of the dead and make men fall in love with them.
