One of the pleasures of a great museum like the Met is that you can take in things from such very different times and climes. Today was no exception. We'd gone knowing we'd see Cristobal de Villalpando’s 1683 altar painting from Puebla, and take a peek at the Costume Institute's Rei Kawakubo show, already worlds apart in so many ways, but we didn't know we'd be most charmed by a little exhibit of treasures of the northern Renaissance.
