Was Picasso a modern Midas who not only turned the trash of everyday life into the gold of Cubist collage but also gave new value to the work of Old Masters?

Krauss brings Picasso's pastiche of other artists brilliantly into focus as the "sublimated" underbelly of Cubism, refashioned in the bright, clean style of Picasso's neoclassicism--a defense that is its own form of practicing the forbidden.
