Abstract: Despite the prevalence of audience-centred drama criticism, very little is actually known about the composition or nature of theatre audiences in antiquity. Metatheatrical passages in Plautus’ and Terence’s comedies in which the audience is described or addressed are usually treated as historical evidence for real-life theatre audiences in Republican Rome. This article argues that it is preferable to treat the comic audience as a fictional character. The scripted audience is recurrently portrayed by the comedians in a far-fetched and anti-realistic manner: it can be treated as a stereotype, along the other ‘stock’ characters of Roman comedy.
