In 2001: A Space Odyssey, monoliths are mysterious objects created by extraterrestrials. In art, these extraterrestrials are the minimalists of the 1960s and 1970s, who created emotionless units of finely manufactured form: monoliths. What do they mean? Miami artist Bert Rodriguez changes the question with Weeping Monolith, a tall black fiberglass slab, hand waxed, with a hole that leaks a drip of water every few minutes. You wait, staring at the mute thing, and when the tear finally falls, the question is, do you believe? And you thought minimalist boys don't cry.
