These two miniature globes were made by Richard Cushee, a London globe maker. The globes can be rotated and adjusted on their bras mountings with respect to the small Moon and Sun orbs attached by curved arms. A celestial globe is a three-dimensional model of the heavens on which the stars are plotted on the outside of a sphere. By using the rings and dials it is posible to read the age of the moon, the time of day, and the movements of the sun, moon and stars at various latitudes. A terrestrial globe is a three-dimensional depiction of the Earth showing its geography and the political boundaries of its nations. It is used to illustrate the Earth's rotation and explain the basis of day and night.
