I recently dropped in at the National Academy Museum, on Fifth Avenue at 89th Street, to view “Reconfiguring The Body in American Art 1820-2009.” On view until Nov. 15, it features 160 works grouped by themes and concerns. Self-portraits, portraits, sculptures, etc. I got lots of ideas of things to do with photography from some of the most recent works. Anyway, it’s against the rules to photograph anything in the galleries, but the statue of Diana that graces the rotunda is fair game. I forget who sculpted her, but another casting is in some mansion somewhere being enjoyed by the people who own it. I couldn’t resist. So along with a recommendation that you can see lots of shows elsewhere that don’t equal the one currently up these stairs, you get a peek at Diana.
