Simon Dinnerstein's Fulbright Triptych is so symmetrically a harmony and so richly a composite of genres (family portrait, still life, landscape, and a collage that amounts to a complex poem) that its anomalies aren't immediately apparent. He himself has pointed out that it's a painting by a graphic artist (and his Fulbright project is there on the table, dead center, a copperplate engraving called Angela's Garden), the baby on his wife's lap had not yet been born (his daughter, Simone, now a con-cert pianist), and what we're looking at is a serene Jewish family in a country that slaughtered six mil-lion Jews from 1933 to 1945. And among the fifty-seven images thumbtacked to the wall is an exit visa from Russia, dated 1918. The Dinnersteins, like the Chagalls and Kandinskys, the Einsteins and Panofskys, move about in the turbulences of history.
