'In Excommunication and Outlawry in the Legal World of Medieval Iceland Elizabeth Walgenbach sets forth the argument that outlawry in medieval Iceland was shaped by the conventions of excommunication. This legal history engages with developments in canon law, law codes from Iceland and neighboring countries, and contemporary sagas and their sources and transmission [...] This is an interesting book, and I do find the central argument compelling, particularly in light of the case studies presented in its defense. It will be of interest to scholars of legal history, outlaw studies, and Old Norse/Icelandic literary and cultural studies, and stands to produce further and lively scholarly discussion regarding the relationship between canon and secular law in medieval Iceland.'
