Abstract

Use of rhetorical figures has been an element of persuasive speech at least since Gorgias of Leontini, for whom such deliberate deviations from ordinary literal language were a defining feature of what he called the ‘psychagogic art’. But must we consider figures of speech limited to an ornamental and merely stylistic function, as some ancient and still many modern theorists suggest? Not according to contemporary cognitive rhetoric, which proposes that figures of speech can play a fundamentally argumentative role in speech by evoking a level of shared meaning between speaker and listener, and simultaneously by affording the possibility of reorganizing this common ground. This paper argues that, in Latin literature, zeugma—the ‘linking together’ of two elements with a third that is semantically compatible with only one of them—can and very often does operate argumentatively, and that it does so by surfacing figurative relationships that normally remain below the conscious awareness of Latin speakers and by imparting a certain structure to these relationships. What very often motivates the selection of elements within zeugma—and what makes zeugma more than simply a stylistic device—are in fact metaphorical structures that are highly conventionalized in Latin's semantic system. In tapping into symbolic associations that are deeply entrenched in the language and thought of Latin speakers, zeugma therefore provided a ready-made device for constructing arguments in context.
