To enter the world of Nonnus’ Dionysiaca, the greatest and most influential Greek poem of the fifth century CE, is to enter an echo chamber of Greek literature and engage with a swirling repertoire of mythic narratives. The erotic narratives of Dionysus and his entourage have to be read through this formative poetics – and so it is here, with poetics, that I will begin my travel towards one of ancient poetry’s most bizarre scenes of lustful, fondling, inappropriate desire in action. If any writer of late antiquity reforms the form of epic, from within, as it were, it is Nonnus, whose forty-eight books add up to the forty-eight books of the Iliad and Odyssey combined, but whose narrative discourse, narrative structuring and even verse forms radically disrupt and remould what is understood by the tradition of epic.
