On Monday we went to the Boston MFA to see the Titian, Tintoretto, and Veronese: Rivals in Renaissance Venice exhibition.
It was one of the most interesting exhibitions of this form of art I've ever seen. And these guys were certainly masters at their trade. The explanatory displays with general information as well as one for each work were really well done showing how these three 16h century artists competed and influenced each other. There were several instances of the same scene by each of the artist hung next to each other. There were also several painting where extensive Xray analysis had been done which revealed all sorts of changes in the painting as they were done - and again very well explained and illustrated.
The exhibit closes Sunday so if you haven't seen it there are still a few days to catch it (for locals).
Now I recall I did get an audio guide for a Newport mansion tour and it was really very interesting so perhaps in the future I'll try one at the museum.
