David Hockney's 1999 Lecture on Old Masters' Use of Lenses Revisited

During a 1999 presentation at Columbia University and the Metropolitan Museum of Art, David Hockney posited that artists of the Renaissance, starting in the 1500s, frequently utilized lenses and optical instruments to assist their drawing processes. He suggested this practice accounts for the lack of clumsy drawing in Western art for nearly four centuries until the lens was forsaken by Cézanne and the Impressionists in the 1870s. Hockney cited Dürer's 1525 lute engraving, Holbein's 1533 "The Ambassadors," and Caravaggio's 1590 lute painting as proof of advanced lens usage. He also referenced Raphael's 1518 portrait of a pope with a lens and Velázquez's 1650 pope portrait. Hockney argued that recognizing this link enhances the relevance of art today, particularly as digital imaging revives drawing through photography. This lecture was co-sponsored by the National Arts Journalism Program, The School of the Arts, and the Department of Art History at Columbia. His theory, later detailed in his 2001 book "Secret Knowledge," faced skepticism from computer experts, as noted by The Sunday Herald and The New York Times.
