Here's some proof Mille-from 'The London Review of Books':
"Depictions of punishment figure prominently in images of ancient Greece: Prometheus bound to a mountainside in the Caucasus, his liver eagle-meat, for stealing fire, mankind punished with womankind for receiving said stolen goods; Ixion revolving across the sky tied to a winged wheel, recommending to anyone who would listen the importance of respecting one's host; Erysichthon ravenously hungry, beginning to eat himself; Andromeda tied to a rock, tasty morsel for a sea-monster, because of something her mother said; Niobe petrified, watching her children die one by one of supernatural causes because of something she said herself; Cassandra unbelieved. Probably the most sublime image of punishment is Socrates drinking hemlock in prison and discovering opportunely the undying soul.
Probably the most ridiculous is the schoolboys' favourite piece of vocab, rhaphanidosis, a punishment inflicted on adulterers by cuckolded husbands, a radish up the arse." http://www.lrb.co.uk/v22/n16/davi02_.html
