Following the example of medieval codes, the cover contains the best examples of treatises on monsters written in the Middle Ages: “The Book of Beasts and Monsters” by an unknown author of the 8th century, in-depth studies on dragons, scorpions and sea monsters by the 13th century encyclopedist Thomas of Cantimpre, geographical calculations by Honorius of Augustodon (XII century), who settled monsters throughout the Earth's Circle, and a very relevant message from the monk Ratramnus (VIII century), considering the question of whether or not to baptize dog-headed people.
