A model or the earth or the heavens, in which a map is pasted on to a sphere. Globes turn on their axis mimicking the movement of the Earth or heavens. They were often made from plaster on a wood and paper frame, or from metal. The map pasted onto this sphere was usually painted. Globes can be used for navigation, for determining one's position relative to a place or time, and to make many other calculations. They come in a huge range of sizes, from pocket globes to table globes, to huge floor globes. The Sunderland Collection contains a beautiful pair of floor globes by Joan Blaeu.
