Oeuvres poetiques II, by Christine de Pisan. Appears to be the original French.
American Cookery: The Art of Dressing Viands, Fish, Poultry, and Vegetables (1796). Long post-period, but still old enough to be interesting to the food-history crowd.
Abélard, Tome I, by Charles de Rémusat (1845). In French -- a modern book about period.
