This article argues that Virgil includes an allusion to the fourth-century censor Appius Claudius Caecus in Book 8 of the Aeneid. Three pieces of evidence point to this allusion: (1) wordplay, especially the near echo of ‘Caecus’ in ‘Cacus’; (2) semantic associations between Cacus and darkness; and (3) repeated references to sight and Cacus’ eyes. By invoking the memory of Appius, whose blinding in 312 b.c.e. allegedly came at the hands of Hercules as punishment for transferring control of the god's (...) rites at the Ara Maxima to the state, Virgil underscores the importance of properly observing religious rituals. This aligns with Evander's original intent with the Hercules–Cacus story to prove to Aeneas and the Trojans that the Arcadians’ religious practices are no uana superstitio (8.187). (shrink)
