Agustín de Rojas (1949-2011) is the patron saint of Cuban science fiction. A professor of the history of theater at the Escuela de Instructores de Arte in Villa Clara, he authored a canonical trilogy of novels consisting of Espiral (Spiral, 1982), for which he was awarded the David Prize; Una leyenda del futuro (A Legend of the Future, 1985); and El año 200 (The Year 200, 1990), all of which are scheduled for publication in English translation by Restless Books. While he was heavily influenced by Ray Bradbury and translated Isaac Asimov into Spanish, de Rojas aligned himself mostly with Soviet writers such as Ivan Yefremov and the brothers Arkady and Boris Strugatsky . After the fall of the Soviet Union, de Rojas stopped writing science fiction. He spent his final years persuaded-and persuading others-that Fidel Castro did not exist.
