As someone who lives two blocks away from the Rothko Chapel I couldn't let today pass without acknowledging it's the anniversary of his death. Blimey if Jonathan Jones only figured out that Rothko's death gave his paintings gravity, he wasn't looking at the paintings.
You can see why the Catholic St. Thomas's University (round the corner too) opted not to use Rothko for their chapel (Philip Johnson instead). His paintings and the chapel space are the real thing.
And what is that?
Disturbingly intimate raw flesh, of course.
