The life and the adventures of Brendan – seafaring saint from Ireland – have been told, rewritten and re-narrated in Western Europe for centuries. The contributions in this volume, result of an international Brendan conference in Flensburg, explore the transformation of the figure in a multiperspective way. Renowned scholars examine multiple phenomena and contexts of the Brendan tradition: cross-connections to Celtic narratives; the location of the Brendan Islands in cartography; aspects of narrative motifs, mediality, and communication history such as the bridle-thief episode, the pictorial programmes of the manuscripts and prints, the saint’s dialogues with his monks, the foundations of the legend in the manuscript culture of the Middle Ages and monastic reading practices, as well as the complex of widespread pictorial testimonies.
