It’s not true. Alison, five husbands, hypersexual, the Wife of Bath an ordinary woman, a woman who existed, even in composite, at all? BULLL SHIT!
Were the Canterbury Tales written by a woman, ordinary or extraordinary? Nah. Written by a guy for a guy and guys. Geoffrey Chaucer was commissioned to write WoB by a wealthy nobleman for his erotic entertainment. So Chaucer executed the commission. Executed it artfully, the poetic form, the rhyming, the surpassingly clever puns. It is art but not art that imitates life. Never intended to be. Intended to be humorous jack-off material for his benefactor and his noble buddies. The End.
