The title of this work, Celestial Navigation, refers to the practice of mapping or charting a course to guide a boat across the ocean, or perhaps a spaceship as it travels around the universe, past planets, comets, asteroids, stars, and galaxies. Inside this box, a white clay head attached to a piece of wood might be a spaceship, floating across part of a map of the stars. The head was originally part of a clay pipe used for blowing soap bubbles. Perhaps the painted cork ball at the top left represents a planet. The drinking glass on the right holds four glass marbles with blue swirls. Cornell left it up to you to imagine what they might stand for.
