The Cloven Viscount (Italian: Il visconte dimezzato) is a fantasy novella written by Italo Calvino. It was first published by Einaudi (Turin) in 1952 and in English in 1962 by William Collins, with a translation by Archibald Colquhoun.

A landmark new translation of a Calvino classic, a whimsical, spirited novel that imagines a life lived entirely on its own terms Cosimo di Rondó, a young Italian nobleman of the eighteenth century, rebels against his parents by climbing into the trees and remaining there for the rest of his life. He adapts efficiently to an existence in the forest canopy—he hunts, sows crops, plays games with earth-bound friends, fights forest fires, solves engineering problems, and even manages to have love affairs. From his perch in the trees, Cosimo sees the Age of Enlightenment pass by, and a new century dawn. The Baron in the Trees exemplifies Calvino’s peerless ability to weave tales that sparkle with enchantment. This new English rendering by acclaimed translator Ann Goldstein breathes new life into one of Calvino’s most beloved works.

The Nonexistent Knight (Italian: Il cavaliere inesistente) is an allegorical fantasy novella by Italo Calvino, first published in Italian 1959 and in English translation in 1962. The tale explores questions of identity, integration with society, and virtue through the adventures of Agilulf, a medieval knight who exemplifies chivalry, piety, and faithfulness but exists only as an empty suit of armour.

Un'armatura vuota animata da uno spirito invisibile che riesce a farsi accettare tra i Paladini di Carlo Magno, un visconte diviso a metà da una palla di cannone che si scinde in una parte buona e in una cattiva, un barone che, per sfuggire a un rimprovero, si rifugia sopra un albero e passa in mezzo agli alti rami tutta la sua esistenza.
