A Void (1994). His novella Les revenentes (1972) is a complementary univocalic piece in which the letter "e" is the only vowel used. This constraint affects even the title, which would conventionally be spelt Revenantes. An English translation by Ian Monk was published in 1996 as The Exeter Text: Jewels, Secrets, Sex in the collection Three. It has been remarked by Jacques Roubaud that these two novels draw words from two disjoint sets of the French language, and that a third novel would be possible, made from the words not used so far (those containing both "e" and a vowel other than "e"). W ou le souvenir d'enfance, (W, or the Memory of Childhood, 1975) is a semi-autobiographical work which is hard to classify. Two alternating narratives make up the volume: one, a fictional outline of a remote island country called "W", at first appears to be a utopian society modeled on the Olympic ideal, but is gradually exposed as a horrifying, totalitarian prison much like a concentration camp. The second narrative is a description of Perec's own childhood during and after World War II. Both narratives converge towards the end, highlighting the common theme of the Holocaust. "Cantatrix sopranica L. Scientific Papers" is a spoof scientific paper detailing experiments on the "yelling reaction" provoked in sopranos by pelting them with rotten tomatoes. All the references in the paper are multi-lingual puns and jokes, e.g. "(Karybb & Szyla, 1973)". David Bellos, who has translated several of Perec's works, wrote an extensive biography of Perec: Georges Perec: A Life in Words, which won the Académie Goncourt's bourse for biography in 1994. The Association Georges Perec has extensive archives on the author in Paris. In 1992 Perec's initially rejected novel Gaspard pas mort (Gaspard not dead), which was believed to be lost, was found by David Bellos amongst papers in the house of Perec's friend . The novel was reworked several times and retitled and published in 2012; its English translation by Bellos followed in 2014 as Portrait of a Man after the 1475 painting of that name by Antonello da Messina. The initial title borrows the name Gaspard from the Paul Verlaine poem "Gaspar Hauser Chante" (inspired by Kaspar Hauser, from the 1881 collection Sagesse) and characters named "Gaspard" appear in both W, or the Memory of Childhood and Life: A User's Manual, while in MICRO-TRADUCTIONS, 15 variations discrètes sur un
