A biographical digression on the Cumaean tyrant Aristodemus Malacus in Dionysius' Roman Antiquities has elicited widespread speculation about the existence of an early Greek source for events in Italy contemporaneous with the origins of the Roman Republic. The communis opinion about the importance of this hypothetical ‘Cumaean chronicle’ warrants reconsideration on two grounds. First, the events in question fall well before the development of Greek historical writing concerned with contemporary events. Second, we must not overlook the potential impact on the tradition of Roman historians who wished to integrate their city's early history with that of the wider (Greek) world.
