The Crusades and Nature: Natural and Supernatural Environments in the Middle Ages explores the intersection of crusader studies and studies of nature. The volume addresses encounters with, responses to and representations of a broad variety of phenomena: celestial objects and events; familiar and unfamiliar fauna and flora; seascapes and landscapes; the elements and the seasons; etc. It introduces readers to crusaders’ actual, but also largely or entirely imaginary encounters with natural phenomena, as well as literary references to nature in crusader sources more generally (such as, for example, animal metaphors). Finally, this project investigates the relationships between the natural and the supernatural and between nature and human-made environments. The volume will define “crusades” broadly, to include not only crusades to the East, but also crusades to frontier regions such as the Baltic and Iberian peninsula and extends to representations of crusades and nature in later medieval and early modern sources.
