Pahgedenaun is a work by Robert Houle, an internationally-acclaimed Saulteaux artist and grew up in the community of Sandy Bay First Nation, on the western shore of Lake Manitoba. His real name, his Saulteaux name, is Blue Thunder, not used when he entered residential school at age seven. Pahgedenuan is a Saulteaux word expressing the self-defining and self-determining act of “letting it go from your mind” embodied in this 9 x 10.5 hardcover publication, which brings together drawings and installations of his childhood suffering. The drawings express “agony that is not yet language or no longer language” (Houle, 2019) In these works, Houle addresses the traumas he experienced as a child while attending the residential school run by the Missionary Oblates of Mary Immaculate in operation from 1905-1970 - an architecture of assimilation. Original texts are accompanied by colour plates, a biography of the artists, and a brief history of the Sandy Bay Residential School. He has exhibited extensively since the early 1980s and his work is represented in numerous collections including the National Gallery of Canada, Art Gallery of Ontario, Remai Modern, Canadian Museum of History, National Museum of the American Indian (Washington, D.C.) and Museum of Contemporary Art (Sydney, Australia). These profoundly powerful and unsettling art works embody acts of memory, truth-telling, survivance and healing.
