The Caravaggisti (or the "Caravagesques") were stylistic followers of the 16th-century Italian Baroque painter Caravaggio. His influence on the new Baroque style that eventually emerged from Mannerism was profound. Caravaggio never established a workshop as most other painters did, and thus had no school to spread his techniques. Nor did he ever set out his underlying philosophical approach to art, the psychological realism which can only be deduced from his surviving work. But it can be seen directly or indirectly in the work of Rubens, Jusepe de Ribera, Bernini, and Rembrandt. Famous while he lived, Caravaggio himself was forgotten almost immediately after his death. Many of his paintings were reascribed to his followers, such as The Taking of Christ, which was attributed to Honthorst until 1990. It was only in the 20th century that his importance to the development of Western art was rediscovered. In the 1920s Roberto Longhi once more placed him in the European tradition: "Ribera, Vermeer, La Tour and Rembrandt could never have existed without him. And the art of Delacroix, Courbet and Manet would have been utterly different". The influential Bernard Berenson stated: "With the exception of Michelangelo, no other Italian painter exercised so great an influence."
