Contributed by David Carrier / Rebuilding seems to be a cyclical occurrence for older art museums. The collection expands, styles of display change, more capacious restaurants and shops may be needed. Older museums have to construct new galleries. To the original European galleries, entered atop the stairs at the entrance, the Metropolitan Museum of Art added space for Islamic art, contemporary work, and Asian paintings. Alternatively, a wealthy museum can rebuild almost from scratch, as MoMA has repeatedly done. Yet, for most of the time I have been going to art museums, New York’s Frick Collection has been basically unchanged, an island of stability. I remember once being shocked that one of its masterworks – Rembrandt’s The Polish Rider – was away on loan. No other major New York art institution has remained basically the same over such a lengthy period, celebrating idiosyncratic displays that mix sacred and secular works in a luxurious setting. Henry Clay Frick had a great eye.
