Heliodorus’ Ethiopica, discussed in Chapter 10, still awaits its discovery by scholars of ancient aesthetics. The latest of the five fully preserved ancient Greek piercingly reflects on the aesthetics of deception. After a close reading of a passage from book 3 that sharply juxtaposes deceit and aesthetic illusion and simultaneously intimates their similarity, I will explore their blending together in the Athenian novella. The aesthetics of deception also pertains to the Ethiopica themselves, which are designed to enthral the reader and simultaneously threaten to dupe her. A Platonic intertext that evokes the condemnation of poetry in the Republic highlights this danger. At the same time, Heliodorus recasts the aesthetics of deception differently from Plato and suggests an allegorical reading of his novel that envisages aesthetic illusion ultimately as a means of overcoming deception.
