Abstract:A writer’s readings can say a lot about their own aesthetic preoccupations, particularly when they resurface in their works. The marquis de Sade was an important source of inspiration for Beckett, especially for Comment c’est, with its many echoes of the Cent Vingt Journées de Sodome. This comparative study will localise the Sadean source in the text, to allow for a better understanding of the intertextual strategies at work in this resolutely postmodern universe.
