One day last year, on a trip to Washington, D.C., I visited two museums: the National Gallery of Art and the Museum of the Bible. These two museums sit only a short distance away from one another near the National Mall, but in focus and feel they differ greatly. The National Gallery, founded 80 years ago, houses one of the world’s most important collections of Western painting and sculpture. The Museum of the Bible, by contrast, is only a few years old and much less prepossessing. Its collection consists mostly of reproductions and multimedia exhibits on the Bible's history and continuing social and cultural impact. The contrast between these two museums is stark; and I imagine the subset of people who visit both is quite small.
