Yesterday I took my daughter to the museum at Dumbarton Oaks in Georgetown. It’s privately funded and thus was not affected by the (recently concluded) government shutdown.
The museum is small, but it features a wonderful collection from the Byzantine Empire and an impressive exhibit of pre-Columbian American artifacts. It also has, tucked away in the corner of one of the rooms, this marvelous painting by El Greco:

What struck me was that the painting manages to convey great emotion even though both Mary’s and Elizabeth’s faces are almost totally obscured. Well worth the schlep to Georgetown if you live in or are visiting the D.C. area.
