Ayutthaya
At the Salem Peabody Essex Museum -- a big, delightful collection of the great age of sail and life in an early-American entrepot -- there's an major exhibit of the art of Ayutthayan Thailand, 1350-1800. Extremely well mounted, the exhibit is not explained as well as I'd like, but it's great to look at and has more documentation than you'd expect.
I'd be interested in suggestions for a readable book on Ayutthaya.
