The book examines the diachronic change of time perception throughout Anglo-Saxon England, with the conversion as a turning point. It draws evidence from a variety of sources, in particular from a close reading of Bede’s historical writings and his treatises on time, from Old English poetry, especially The Dream of the Rood, The Phoenix, The Wanderer, Beowulf, The Ruin, Deor, from the literature of the Alfredian period, and from the lexical and statistical analysis of Old English time words. It offers insights into the complexity of time in the Anglo-Saxon context, and shows how the change of time can help to understand the conceptual system of the Anglo-Saxons.
