In 1940, Adolfo Bioy Casares published La Invención de Morel [The Invention of Morel], a novel that can be considered as one of the most important works of twentieth-century Argentinian fantastic narrative. Since the novel portrays competition between different media, it is not surprising that this work has been adapted to several other media: visual arts, plays, opera, and several feature films, the first and still the best known being L'Année dernière à Marienbad [Last year in Marienbad] (1961). The latest incarnation of La Invención de Morel is the first comic version, created by Jean Pierre Mourey (2007). This article discusses Mourey's adaptation of the novel and the specific possibilities of the comic genre. Special attention will be paid to the conception of time, the manipulation of various media, and the competition between the written word and images which are at the heart of Bioy's novel, and the extent to which the French cartoonist's rendering of these aspects of the work is successful.
