Sharing images of paintings and sculptures by the greatest artists of the time was not as easy as pressing a button on an iPhone during the Renaissance. Jamie Gabbarelli, curator of prints, drawings, and photographs at the Rhode Island School of Design’s Museum of Art, argued during his lecture at the National Gallery of Art in Washington, D.C. that Renaissance innovation with prints broke with the past in crucial ways. His exhibit currently in the West building of the National Gallery explores the question of what happens when an image is shared with the world.
