Greenberg had this to say about what he regarded as Pollock’s major achievement:
“It wasn’t the space. I think the shallow illusion of depth had Cubist antecedents, and of course there was Miró’s indeterminate space. When Bryan Robertson writes about a new kind of space he’s full of shit. It’s the all-overness that’s gotten into contemporary taste. It’s become what one demands of advanced painting. Jackson brought this to head more than anyone.”
About the space maybe so, maybe not; about contemporary taste absolutely right. And now those who care about art are looking for something else.
