Hmmm. I don’t think Duchamp would have called himself a surrealist. He definitely started out in a more Cubist style, but never joined the Cubist group directly. He hung out on the fringes, or so I’ve read. Then, later, he decided he hated “retinal” art — his term — and that lead to all kinds of oddness. Where that happened in relation to surrealism, I am not exactly sure. I know that Duchamp and Dali were longtime friends, though. How that played into their respective art… I have to leave that for others at this point. I am still too new at this to have as useful opinion.
I agree, though, that there is a good chance Duchamp (and other artists of the time) were just thumbing their noses at everyone. There are some that suggest these movements were a reaction to WWI, but Cubism — at least — started before WWI, so I dunno. Surrealism seems to have started after the war. Duchamp spans the entire period, and I haven’t yet figured out when he went from being a painter to thumbing his nose at the powers that be in the art world.
As for de Chirico, I note that one of his paintings (Gare Montparnasse) was one that came up in Art History last semester. Disturbing thing, on a number of levels. A google image search doesn’t bring up anything by him that looks Cubist to me, but that doesn’t mean all that much.
Ah well… I guess I will create a collage of some sort that thumbs it’s nose at something. Or maybe not. It’ll work out. C’est la vie.
