There's actually a psychological condition, Stendhal Syndrome aka "Florence Syndrome" brought on by the reactions some people experience when exposed to profound emotional triggers (usually artistic).
Interesting. I probably didn’t know enough about the art I was looking at to achieve “Florence Syndrome” stage, although I recognized a lot of the artists’ names. I DID reach the level of “tired & hungry”, so the kid (my oldest daughter) and I stepped across the street and had a meal. Still...well worth the trip.
