From 1959 to 1967 Calvino edited with Elio Vittorini the magazine Il Menab di letteratura. In 1952 he travelled to the Soviet Union and in 1959-60 to the United States. In 1967 he moved to Paris, and then to Rome in 1979. While living in France, Calvino met the Argentinian translator Ester Judith Singer (Chichita), they were married in 1964 in Havanna. Calvino died of cerebral hemorrhage in Siena, on September 19, 1985. His later essays Le lezioni americane were published posthumously. From the collection Under a Jaguar Sun (1991), stories on the five senses, 'sight' and 'touch' were never completed. Calvino works in it around five central qualities of good fiction lightness, quickness, exactitude, visibility, and multiplicity. In The Uses of Literature (1980) Calvino noted that there should be a time "in adult life devoted to revisiting the most important books of our youth. Even if the books have remained the same, we have most certainly changed, and our encounter will be an entirely new thing."
