Columbanus (d.615), the Irish monk and founder of such important centres as Luxeuil and Bobbio, was one of the most influential figures in early medieval Europe. His fiery personality led him into conflict with Gallic bishops and Roman popes, and he defended his position on such matters as monastic discipline in a substantial corpus of Latin writings marked by burning conviction and rhetorical skill. However, the polish of his style has raised questions about the nature of his early training in Ireland and even about the authenticity of the writings which have come down to us under his name. The studies in this volume attempt to address these questions: by treating each of the individual writings comprehensively, and drawing on recently-developed techniques of stylistic analysis new light is shed on Columbanus and his early education in Ireland. More importantly, doubts over the authenticity of certain writings attributed to Columbanus are here authoritatively resolved, so putting the study of this cardinal figure on a sound basis.Professor MICHAEL LAPIDGE teaches in the Department of Anglo-Saxon, Norse and Celtic, University of Cambridge.
