A Mark Rothko painting was defaced at the Tate Modern today. Andrew Johnson of The Independent and Hyperallergic report that a man walked up to the work, Black on Maroon, 1958, with a marker pen and tagged it. The painting was gifted to the museum in 1965 by Rothko. The painting was originally part of a series commissioned for the Four Seasons Restaurant in New York. Johnson notes that the series was never exhibited at the restaurant, and upon completion, Rothko decided that “he didn't want his paintings being used as a backdrop for privileged diners.” Police are currently investigating the incident.
