The Science of the Spheres and Heavens

The Square is a right angle, formed by two right lines. It is adapted only to a plane surface, and belongs only to geometry, earth-measurement, that trigonometry which deals only with planes, and with the earth, which the ancients supposed to be a plane. The Compass describes circles, and deals with spherical trigonometry, the science of the spheres and heavens.
