The hagiographical tradition of the Gargano, which concerned the epiphany of the Archangel Michael, is well-established in the Liber de apparitione Sancti Michaelis in Monte Gargano. The same text probably is commissioned by the longboard dukes of Benevento. Later on, the tradition of the sanctuary was amended by the hagiographical dossier of Saint Laurence, bishop of Siponto, and by Greek Metafrasis of the legenda concerned the foundation of the Ecclesia garganica. Consequently, the present work deepens the implantation of the figure of bishop Laurence in the visual culture expressed in the Italian area. It focused on the visual products allocated in the Daunia. Then, it analyzes the productions that represent the saint bishop in Tuscany, where his presence is functional to enhance the role of the bishop in the management of the Diocese. Finally, it considers the frescos in Rome, that concern the legenda of Gargano.
