This article explores the much-debated question of the political impact or potential of theatre from a new angle. Accepting frankly the limitations of a medium which seldom reaches more than four per cent of the population, Temple Hauptfleisch looks instead at the contingent ways in which influence works - creating ‘images’ of authors, performers, venues, companies, and even of specific occasions which work upon audiences and non-audiences alike. The ideas explored in this article were first proposed in a paper read at a colloquium on ‘The Semiotics of Political Transition’, held at the Port Elizabeth Campus of Vista University in August, 1992: although most of the author's examples are thus from the theatre world of South Africa, the major thrust of his argument holds equally well for any contemporary westernized, media-dominated society. Temple Hauptfleisch is Associate Professor of Drama and Head of Theatre Research at the University of Stellenbosch, South Africa. He is co-editor of the South African Theatre Journal and has published widely on the history and theory of South African theatre. © 1995, Cambridge University Press. All rights reserved.
