It is not the word that is the original material of poetry, rather the letter. - Kurt Schwitters

In the war [World War 1.] things were in terrible turmoil. What I had learned at the academy was of no use to me and the useful new ideas were still unready.. .I felt myself freed and had to shout my jubilation out to the world. Out of parsimony I took what I could find to do this, because we were now an impoverished country. One can even shout with refuse, and this is what I did, nailing and gluing it [gluing his collage art] together. I called it 'Merz'; it was a prayer about the victorious end of the war, victorious as once again peace had won in the end; everything had broken down in any case and new things had to be made out of the fragments; and this is Merz. [quote, 1930]

The medium is as unimportant as I myself. Essential is only the forming.. .I take any material whatsoever if the picture demands it. When I adjust materials of different kinds to one another, I have taken a step in advance of mere oil painting, for in addition to playing off color against color, line against line, form against form etc., I play off material against material, wood against sack clothes.

Kurt Schwitters is the inventor of Merz and I, and aside of himself, he recognizes no one as a Merz artist or an I artist with highest regards.
