"Rembrandt" rings a bell but I had no idea this painting even existed (until you wrote about it and of course hearing you mention it in class).  I think it's really interesting he decided to paint the human psyche.  There is a lot of literature, as you mentioned Jung, but rarely do people paint to represent something intellectually.  Or, that I know of, at least.  I agree this should be preserved for a time capsule because it represents a time where there was a birth of intellectuals.  People began straying from the church and really broke the norm.  What were some common intellectual thoughts at this time period?  What do you mean by timeless?
