An angel’s power in a bishop’s body: the making of the cult of Aubert of Avranches at Mont-Saint-Michel

In the eleventh and twelfth centuries, the Benedictine monks of Mont-Saint Michel promoted the cult of Aubert of Avranches, the abbey’s legendary co-founder, and used his newly rediscovered relics as a means of accessing the patronage and power of the elusive, incorporeal archangel Michael, the community’s other founder. Texts, images, the strategic placement of Aubert’s relics throughout the abbey church reinforced the association between these two saints, rendering Aubert more powerful and Michael more accessible. This local study of the interaction between these two cults at the abbey of Mont-Saint-Michel suggests that medieval monastic uses of relics were more creative and varied than is generally recognized and that relationships between saints within a single cultic environment could be extremely complex and unstable.
