When Boston-area artist Linda Burke first fired a gun, it kicked back, offloading a hot cartridge that went down her shirt. As she scrambled to save herself, she forgot that she was holding a gun with the safety catch off. She had a new sense of lives being "thin and fine as filament." She considered "that whether it's a gun or an act we do, or an illness and how we respond—whatever we do affects another thing." For Untitled 7, she placed a small copy of Leonardo da Vinci's Face of Christ study on top of the "Scoring for Training" box.
