The experience in my village of Deetziyamah and Acoma Pueblo was readily accessible. My mother was a potter of the well-known Acoma clayware. My father carved figures from wood and did beadwork. There was always some kind of artistic endeavor that Native American people, set themselves to, although they did not necessarily articulate it as "Art" in the sense of Western civilization.
