The new curator placed surpassingly ugly statues in the large niches, which were better left empty.
The facade of the Metropolitan Museum of Art, designed by Richard Morris Hunt in 1902, contains four large niches that might display sculpture but have traditionally been left empty. This was prudent good taste on the Met’s part, since sculpture on buildings is a tricky business that few artists in our age of individualism would understand: Facade sculpture must be part of a harmonious whole. If a piece draws undue attention to itself, it detracts from the building. And buildings, as architecture, have long been the most important, the most pervasive, and also the least consciously respected form of art.
The concept of the harmonious whole may be outdated. It comes from an age when an entire city of artists might devote their lives to a single, collective project: The sculptural niche is a trope of the cathedral, where the building and its adornment were in total alignment, under the unified direction of the master mason. In the absence of that perfect alignment, those exterior spaces might better contain nothing at all. Which is perhaps why, after the British rashly smashed all their niche sculpture during the Reformation, they decided to leave the niches empty rather than replace them with something new. This emptiness was later copied, perhaps unwittingly, by American architects in their homage to the British style, which is why our neo-Gothic college campuses are replete with little sculptural tabernacles and niches, all of them bare.
This is not to say the Met couldn’t have found some appropriate sculpture with which to decorate their facade: They might, for example, have drawn from their ample supply of Rodin bronzes. But if they pulled those Rodins out of their convenient, indoor galleries and stuck them 30 feet above the ground, it would be hard to get a good look at them. And so the sculptures would enhance the building at their own expense.
