Johann Geiler von Kaysersberg was a theologian who preached at Strasbourg Cathedral in France. In 1508, he gave a series of sermons which were later published in this book, called Die Emeis (The Ants). On the third Sunday of Lent, Geiler delivered this sermon on werewolves. He listed seven reasons why they might attack and explained that they especially liked to eat children. For Geiler, the likelihood of an attack was influenced by the werewolf’s age and its experience of eating human flesh. Shown here: f. 41r
