Michael Fried, J. R. Herbert Boone Professor and director of the Humanities Center, The Johns Hopkins University In a series of six lectures, Michael Fried offers a compelling account of what he calls "the internal structure of the pictorial act" in the revolutionary art of Michelangelo Merisi da Caravaggio. The accompanying publication, The Moment of Caravaggio, is available for purchase from the Gallery Shops. In this audio podcast of the fourth lecture, originally delivered at the National Gallery of Art on May 5, 2002, Professor Michael Fried explores how two polar entities in Caravaggio's art—absorption and address—lead to the emergence of the gallery picture.
