In traditional Chinese cosmology the earth was square and the heavens round, and thus Fuxi holds a set square to draw the former, and Nuwa a pair of compasses to draw the circle of the earth. The sun is between them, the moon at the bottom and constellations down both sides, including one to the right recognizable as the Great Bear.
