Roman comedies transcend the isolated pockets of time in which they are set. Their characters have histories, and their plots are influenced by past events. The audience peers into these with voyeuristic curiosity, as does Periphanes, the senex (‘old man’) of Plautus’ Epidicus: ‘It would be good if people had mirrors … they could then think about how they lived their lives long ago in their youth’ (Plaut. Ep. 382–7). The suspense of comedy lies, however, in the vagueness of these very histories; if the figures of the Epidicus had truly possessed ‘mirrors’, Periphanes would have instantly recognised the slave-musician Telestis as his daughter and there would be no narrative to speak of. The complex relationship which comedy holds with its pasts is therefore advantageous to the audience, who derive no little laughter from watching comic characters grapple with their histories.
