Globes were created out of the desire to collate as much data about the world as possible and present it in a transparent manner in a larger context. They not only represented the earth in the form of a sphere, but in some cases combined it with a map of the heavens. Such miniature terrestrial and celestial globes allowed you to magic the world out of your pocket, so to speak, are were primarily produced as luxury objects for royal patrons. The pocket globe made in 1736 by the Nuremberg physicist and mathematician Johann Gabriel Doppelmayr and the engraver Johann Georg Puschner naturally only contains a selection of data. It would be impossible for the small globe, which measures just ten centimetres in diameter, to convey all the topographical and astronomical knowledge of the day.
