Last week, while some BlackBookers were sitting outside our East 19th Street offices in Manhattan, smoking cigarettes and waiting for Chris Noth to walk by again, pieces of the decorative facade from the building opposite fell five stories to the ground. Fortunately, no one at tapas bar/resto Pipa had yet been seated at the sidewalk cafe, and no one was harmed. But more masonry fell elsewhere in the city: Late last night, a 15th-century terra-cotta sculpture of St. Michael the Archangel fell off the wall in the Metropolitan Museum of Art’s European Paintings and Decorative Arts Galleries. Again, no one was harmed (except St. Michael) — though again, the lack of casualties was strictly a coincidence of timing. Art kills, people. Or it wants to.
