Book excerpt: 1) This is the first monograph systematically to apply modern principles of ecotheology to early medieval literature and religious texts. 2) Whereas Dale (2017) provides ecocritical and ecotheological readings of the Exeter Book riddles alone, this monograph performs ecotheological readings of poems from multiple genres across the manuscript, and of the manuscript itself. 3. This book contributes to the field of pre-modern environmental humanities by considering the impact of medieval theology and environmental apocalypticism on some of the earliest examples of the English literary tradition
