The first Medieval literature I read was The Art of Courtly Love. The second book was Christine's The Book of the Duke of True Lovers. She subverts all the tenets given for courtly love to show its faults. She is requested to write the story of the Duke and she uses this opportunity to warn women and let them know the are better things to do than become involved in courtly love. Not a major milestone today, but for a period in time when few people were educated (and unheard of for women) Christine brilliantly uses her postion to her advantage!
