The importance of frames (there are several newly framed works here) is especially evident when we see the difference between two monumental Rembrandts the elegant and restrained wooden frame that surrounds the so-called Noble Slav (1632) makes the gilded 19th-century frame on "Aristotle With the Bust of Homer" (1653) seem needlessly gaudy.
