John was also often shown by himself as an adolescent or adult, usually already wearing his distinctive dress and carrying a long thin wooden cross – another theme influenced by Leonardo, whose equivocal composition, with the camel-skin dress, was developed by Raphael, Titian and Guido Reni among many others. Often he is accompanied by a lamb, especially in the many Early Netherlandish paintings which needed this attribute as he wore normal clothes, or a red robe over a not very clearly indicated camel skin. Caravaggio painted an especially large number of works including John, from at least five largely nude youths attributed to him, to three late works on his death – the great "Execution" in Malta, and two sombre Salomes with his head, one in Madrid, and one in London.
