Last week I promised more on Documenta 12’s dark rooms, and the thought brings me to Spanish-born, Chicago-based artist Iñigo Manglano-Ovalle’s Phantom Truck.

Remember when Colin Powell told the United Nations, in February 2003, that Iraq had mobile biological weapons labs capable of mass destruction? A computer drawing of one of them was presented as “solid intelligence.” Then came invasion. Then came the realization that these things, buried under the ground, weren’t capable of inflicting all that crazy terror.

The artist made a life-sized replica of one of the labs for Documenta. It sat in an unlit room. Because of the dark, and because I’m clumsy, I came this close to running into one of its sharp edges while I was walking, slowly, around it.

I thought how much fun it would be to explain an injury from the real fake weapons lab.
