Uhh, hate to dispute your teacher, but Hades rape-raped Persephone too.
Or at least as much as any of the captive women in the Iliad were rape-raped. Women of the time were aware that captives became the sex slaves of the conqueror, so possibly violence was less necessary than for a modern woman with different expectations.
Well, poop. So much for that example. :-)
Witnesses?
