It was crowded of course, but to see these paintings in person that were painted in the 1500's and 1600's is amazing.
The first time I saw a Caravaggio painting in person, "Supper at Emmaus" was either at the J Paul Getty museum in Malibu for a special show, or it's home at the National Gallery in London. I remember walking into a fairly dark room with the paintings lit. When I saw this painting I just stopped, I was captivated by the light and shadows, the moment of the scene, and of course the hands. It was a wonderful experience embedded in my memory.
