This day in history.
May 30 1431
Joan of Arc is burned at the stake, ostensibly because she "heard voices" and refused to wear female clothing. * compliments of The Rotten Daily*
Though in my opinion, she was most likely mentally ill. People were very stupid back then- even more so than today, and they would believe anything. You don't see people now a days walking up to the crack-addict supposed prophet on the sidewalk proclaiming he is the second coming. If you do, find the nearest toilet and drown yourself. Schizophrenia and some forms of manic depression can cause delusions/illusions and voices.(where is Zyprexa when ya need it) Hell, and if you are smart enough, you get people to play along! You don't get tossed in some asylum to rot away(not yet at least)
But if it is all true that she was hearing the voice of god, no one would ever really know. Mainly because the church proclaimed her a heretic, therefore if you were a devout church follower, the church IS right. *or you go to hell- say your penance please*
