Ecocriticism and Old Norse Studies is the first anthology to combine environmental humanities approaches and the study of premodern Nordic literature and culture. The chapters gathered here present innovative research based on the most recent developments within ecologically informed literary and cultural studies. Covering a wide variety of sources, the volume provides new insights into the Old Norse environmental imagination, showing how premodern texts relate to nature and the environment - both the real-world environments of the Viking Age and Middle Ages, and the fantastic environments of some parts of saga literature. Collectively, the contributions shed new light on the role of cultural contacts, textual traditions, and intertextuality in the shaping of Old Norse perceptions and representations of nature and the environment, as well as on the modern reception and (mis-)use of these ideas. The volume moreover has a contemporary relevance, inviting readers to consider the lessons that can be learned from how people perceived their environments and interacted with them in the past as we face environmental crises in our own times.
