Exceptional set of two globes, one terrestrial, one celestial designed to carry out astronomical experiments
In its vertical axis, the terrestrial globe has a fixed solar ring supporting a train of gears that move a vertical lunar ring, and another one divided into degrees| the globe rotates on itself at an inclination determined by the angle of the ecliptic. The set also includes a mobile arm fixed to the north polar mechanics and a fixed arm with a star at the south pole. On the globe itself, there is a cartouche dedicated to George III and the signature of G. ADAMS (1750-1795). This globe is surrounded by an equatorial ring divided into degrees and two additional rings. Turned brass base.
The second, celestial globe carries the following signature: "A New Celestial Globe by R. Caifhiee 1730". It has the same turned base as the terrestrial globe, and at the pole, gears that can fit into the mechanical framework of the terrestrial one.
Remarkable demonstration set, produced in England during the 18th century.
H: 22.8 and 23.2 in. Circumferences of globes: 34.6 and 35 in.
