Olivier Mosset was in town for the opening of his exhibition at Parapet/Real Humans, a project space run by Amy Granat in a storefront in the Fox Park neighborhood of Saint Louis. On view was a framed set of four lithographs of two thick black stripes on a square of white paper. The set, it turns out, was made for a Swiss Institute benefit in 2004. Granat said the work reminded her of September 11—I suppose any two vertical lines will do that. The artist compared them to an optometrist’s vision test. As someone who can’t see six inches past his nose without glasses or contacts (and who never skips his annual eye-doctor visit), that made more sense.
