Miniature ‘pocket globes’ began to be produced from the second half of the 17th century. Small enough to fit inside a pocket, they were designed to function as curious and educational objects rather than as serious practical devices.
This globe was produced by the prolific German mapmaker Johann Baptist Homann (1664–1705) in around 1700. The globe is housed in a leather-covered case which has charts of the north and southern celestial hemispheres pasted onto the inside.
The globe itself is hollow, and inside of it is a tiny armillary sphere (a model of the solar system) with a band containing the 12 zodiacal constellations, and a miniature sun at its centre.
