22370 Italocalvino           Discovered 1993 Oct. 15 at the Bassano Bresciano Observatory.
Italian writer Italo Calvino (1923-1985) produced fantastic tales such as Il visconte dimezzato (1952), Il barone rampante (1957) and Il cavaliere inesistente (1959). His Le cosmicomiche is a stream-of-consciousness narrative that treats the creation and evolution of the universe.
