Io as Isis: A Lycophronean Myth in Nonnus

This article aims to examine one of the myths belonging to the first part of Nonnus’ Dionysiaca, i.e., that of Io. Starting from the philological analysis of the passages dealing with this myth and adopting an intertextual approach, I will argue that the Panopolitan assimilates Io to Isis following Lycophron, one of the authors employed as a model in his poem. Finally, I will also explain the meaning of this choice inside Nonnus’ work, taking into account its historical context. Nonnus wants to emphasize the role of Dionysus’ lineage in the civilization process, giving it an historical relevance. Therefore, the allusion to Lycophron assimilates Cadmus (Dionysus’ grandfather) to Alexander the Great, who is celebrated as a peacemaker in the Alexandra. Furthermore, Cadmus and his offspring can be connected to the Romans, who, at the time of Nonnus, played the same role in the rising Byzantine empire.
