Castle sold enough drawings in his lifetime that his relatives were eventually able to buy him a trailer, which he used as a studio on the family farm in Boise. His parents and sister and her family appear in some of his strangest drawings as stiff, blocklike figures standing in living rooms and yards. Other works show a breathtaking talent for economy and perspective, such as a drawing of an empty room with a door opening onto a landscape of distant hills, or a still life of dolls arranged on a piano, evoking the quiet intensity of Giorgio Morandi.
Maddeningly for curators, none of Castle’s soot drawings, collages, or small color compositions have titles or dates, although nearly all that survive are believed to have been made after 1931. Castle also made clever paper-and-thread sculptures of birds and other objects, a selection of which appeared in the 2013 Venice Biennale. Although this survey regrettably included only a few of those, it nonetheless gave a rich sense of Castle’s extraordinary gifts.
