Holmes, Jr.; Pilgrims, Heretics, and Lovers, by Claude Marks; Medieval London, by Timothy Baker; The Women Troubadours, by Meg Bogin; Songs of the Troubadours, edited and translated by Anthony Bonner; The Conquering Family, by Thomas Costain; The Devil’s Brood, by Alfred Duggan; The Divine King in England and The God of the Witches, by Margaret Alice Murray; Medieval Woman’s Guide to Health by Beryl Rowland; William Marshal: The Flower of Chivalry, by Georges Duby; and Medieval Holidays and Festivals: A Calendar of Celebrations, by M.
