The Terrestrial Globe is a representation of the Earth with its several divisions of land and water. In order to show the relative position of the various parts of the Earth, and of the motion of the Sun, Moon, and Stars, imaginary lines or circles have been formed both on the terrestrial and celestial globe. ─ The Geography of the Globe (1826)
