My project aims to investigate the concept of ‘wolfishness’ in medieval Scandinavia through an interdisciplinary approach that considers archaeological, literary and scientific evidence. Wolves were among the most impactful animals in Old Norse culture, and the majority of sources that represent them were created in medieval Iceland. However, this species was never indigenous to Iceland and therefore, my thesis explores this tradition tracing it to Norway and Europe. Furthermore, Old Norse culture places considerable emphasis on the similarities and differences between wolves and dogs, which elicits a complex picture that has not yet been carefully addressed. My project analyses this triangular relationship between humans, wolves, and dogs to determine how wolves came to be among the most influential animals in medieval Scandinavia.
