Gerlando di Besançon. Vescovo patrono di Agrigento o anche celebre teologo europeo?

Saint Gerland of Besançon († 1100), patron of the diocese of Agrigento and Norman bishop, enjoys a fame almost exclusive to Agrigento. In his time, however, his sanctity was well known in Norman Sicily to the point of being portrayed in the mosaics of the cathedral of Monreal. Moreover, at Besançon, he was also magister scholarum and the corpus of works which circulated in medieval Europe under the name of Gerland, described by modern criticism as the Computist, could be ascribed to him. In this case, the bishop of Agrigento would have to be esteemed also for the value of his teaching within the debates of the eleventh century concerning the use of dialectic in theology. However, the saint's biography does not resolve all the doubts about this identification. [ABSTRACT FROM AUTHOR]
