Aliénor de Poitiers, daughter of the countess of Poitiers, in France, wrote Les honneurs de la cour (Honors of the Court), a kind of Emily Post for the French nobility. Written between 1484 and 1491, the book outlined the structures and rules of court ritual and the etiquette appropriate to different social classes in a variety of situations and contexts, including the birthing chamber.
