The Praxis of the Tractrix

Abstract

This essay analyzes Zorns Lemma (1962–1970), a film made by American artist Hollis Frampton (1936–1984). Noting Frampton’s use of Robert Grosseteste’s thirteenth-century treatise De luce [‘On Light’] as a key aspect of the film’s soundtrack, the essay argues that Grosseteste’s investigations of light as a medium played a key role in Frampton’s theorization of cinema. As such, his interest in medieval light theories spurred him to develop a powerful, idiosyncratic response to prevailing discourses of media and medium specificity during the 1960s. When examined in light of contemporaneous projects by Pier Paolo Pasolini (1922–1975) and Roland Barthes (1915–1980), Zorns Lemma points up the significance of medieval thought in the period’s conceptions of art and time.
