In 1938 he published his first volume of poetry: Presencia (Presence) and in 1949 his dramatic poem Los reyes (The Kings). When Rayuela was first published in 1963, it brought Cortázar immediately to the critics’ attention. The author was forty-nine years old at the time and was little known, despite having already published seven books: a dramatic poem, a volume of poetry—under the pseudonym Julio Denis—and five volumes of fiction. Rayuela remains his best-known work. For more about Julio Cortázar, see WLT, Vol. 44.1.
