The nave of the Siena Duomo. I know something about Western art history but I'm no expert. Something here is sliding between the baroque and rococo but I couldn't define where the line falls. In any event, the visual effects are overwhelming. The church construction was begun in the 13th and 14th Centuries, and it is mind-boggling to consider the architectural and engineering skill. The decoration developed over the following centuries. It is impossible for even an interested tourist to take it all in.
As mentioned, lots of flying today. May get some photo editing done on the long London - Chicago segment but I don't know when I'll get my next post up.
