Dispensing once and for all with the idea that Ennius’ Sacra historia was an exercise in Scipionic propaganda, this chapter argues that that prose text was integral to Ennius’ vision of Roman history and authorial self-fashioning. Despite the opacity of their transmission by Lactantius, the fragments of the Sacra historia reveal their author as an interpretative innovator exploiting linguistic effects only possible in translation. The way that this text mediates between Greek and Roman antiquities through multilingual interpretes, moreover, reveals a characteristic but underappreciated aspect of Ennius’ creative persona.
