Villehardouin's Conquest of Constantinople is a standard reference work on the Fourth Crusade; it is the first work in medieval French prose. Joinville's life of St. Louis is a classic description of the life and times of King Louis IX; it is written in Old French and is perhaps the best biography written in the Middle Ages.
