Renaissance fresco in San Petronio Basilica, depicting Mohammed being tortured in Hell. http://en.wikipedia.org/wiki/San_Petronio_Basilica Renaissance fresco in San Petronio Basilica, depicting Mohammed being tortured in Hell. http://en.wikipedia.org/wiki/San_Petronio_Basilica Odd thought: in Catholic religious art, saints are usually identified by some symbol (a lamb for Agnes, a dog with a torch for Dominic, the keys for Peter, etc.) Is there a symbol here which shows that it's Mo himself in hell? Just curious.
