From Wikipedia:

Stendhal syndrome, Stendhal’s syndrome, hyperkulturemia, or Florence syndrome is a psychosomatic disorder that causes rapid heartbeat, dizziness, fainting, confusion and even hallucinations when an individual is exposed to art, usually when the art is particularly beautiful or a large amount of art is in a single place. The term can also be used to describe a similar reaction to a surfeit of choice in other circumstances, e.g. when confronted with immense beauty in the natural world.

Bonus!

The Stendhal Syndrome is also a film by the formidable Dario Argento and stars Asia Argento. I may have to watch this; anyone else up for it?
