This monograph examines three aesthetic emotions in Ælfric's Lives of Saints. Drawing on recent research on emotional communities, this research combines methods from Cognitive Sciences and other studies on early Medieval English language and literature in order to explore Ælfric's usage of the terms in the lexical domain of amazement. The main aim of this study is to identify preferred modes of expression that would reveal a series of emotional rules in the context of Ælfric's emotional community. Looking into Ælfric's usage of this lexical domain and how he depicts emotion dynamics in these texts, this monograph shows how the emotion family of amazement is central to the hagiographical genre, and it highlights important emotion-regulation scripts that operate in these texts.
