Duccio di Buoninsegna, Crucifixion Scene from the Maestà Altarpiece

Don't even miss David Hockney's piece, Pictures and power, in the Guardian. For me it runs slightly parallel to Hugo's argument in Hunchback about the death of architecture being hastened by the invention of the printing press. Technology shifts power. Hockney suggests--among other things--that we just might want to pay attention to that fact. One of the Guardian commenters criticizes the painter for being all over the place. So what? So are we.
