THE WITCHES OF TEPOZTLAN (AND OTHER UNPUBLISHED OPERAS) describes the cases of four different and rather obscure operas written by equally obscure composers whose existence, whether fictitious or real, is never confirmed by the author. By intertwining these four stories in the form of a narrative fugue, this book invites the reader to reflect on the conception of a masterpiece, the role that biography plays in turning an author into an antihero or a mythical figure, and the relationship between a work, its author, and its interpreters. PABLO HELGUERA (Mexico City, 1971) is a visual artist. His work, which includes writing and performance, ranges from making phonographic recordings of dying languages to driving across the American continent (The School of Panamerican Unrest). He is the author of The Pablo Helguera Manual of Contemporary Art Style (2005), an etiquette manual for the art world, and the novel The Boy Inside the Letter (2008).
