Boy Bitten by a Lizard is an oil-on-canvas painting from around 1595 by the Italian Baroque painter Caravaggio. It exists in two versions, both believed to be authentic works of Caravaggio; one is in the collection of the Fondazione Roberto Longhi in Florence, while the other, shown here, is in the National Gallery, London. The identity of the sitter (theorised to be Mario Minniti) and the symbolism of the painting have been the subjects of much debate.Painting credit: Caravaggio
