" There is an odd but revealing phrase – ‘in the flesh’ – for seeing art in reality, not reproduction. With Lotto and other Venetian painters it’s almost exact: to appreciate them properly you have to stand in front of them. Only then can you sense the carnal reality of the people they depict, the glistening of their skin, gleam in their eyes, the weight of their bodies, the texture of their clothes. These are physical experiences, because paint is a physical substance: a layer of organic and inorganic chemicals that reflects the light, and consequently changes every time the light alters. There is no substitute for being there. "
