Giovanni Battista Cavalcaselle (born January 22, 1820, Legnano, kingdom of Lombardy and Venetia [Italy]—died October 31, 1897, Legnano, Italy) was a writer on art and, with Giovanni Morelli, founder of modern Italian art-historical studies.
A student at the Academy of Fine Arts in Venice, Cavalcaselle from early youth studied the art treasures of Italy. In Germany (1846–47) he met another art enthusiast, the Englishman J.A. Crowe, and they studied together in Berlin. On his return to Venice, Cavalcaselle took an active part in the Revolution of 1848 against Austrian rule. He was arrested by Austrian gendarmes and narrowly escaped being shot. He then joined the forces of Giuseppe Garibaldi and was taken prisoner by the French in 1849. He arrived in miserable plight in Paris, where by good fortune he again met Crowe, and with Crowe’s help he went to London, where he lived from 1850 to 1857. The two friends worked on a history of early Flemish painters in 1857. In 1864 Crowe and Cavalcaselle published their great work, A New History of Italian Painting, which was followed by A History of Painting in North Italy (1871). Their other joint works were Titian (1877) and Raphael (1882–85). Cavalcaselle’s sketchbooks and notes, preserved in the Marciana Library in Venice, are evidence of his method and range of knowledge.
Cavalcaselle was for some time secretary to Morelli and was his traveling companion when Morelli compiled the inventory of the works of art in the Marches of Ancona for the Italian government. Toward the end of his life, Cavalcaselle was inspector of fine arts in the Ministry of Education in Rome.
