Old English Ecotheology examines the impact of environmental crises on early medieval English theology and poetry. Like their modern counterparts, theologians at the turn of the first millennium understood the interconnectedness of the Earth community, and affirmed the independent subjectivity of other-than-humans. The author argues for the existence of a specific Old English ecotheology, and demonstrates the influence of that theology on contemporaneous poetry. Taking the Exeter Book as a microcosm of the poetic corpus, she explores the impact of early medieval apocalypticism and environmental anxiety on Old English wisdom poems, riddles, elegies, and saints' lives. 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
