The background globe gores are titled Globo celeste calcolato peril corrente anno sulle osservazioni de Sigg. Flamsteed e de la Caille. by Giovanni Maria Cassini, published in Rome, 1792.
Reproduced and assembled from four sheets of globe gores that make up a 12-inch diameter globe, this is a particularly decorative projection of the heavens, with the constellations shown in their classical forms.
The MOVA globes, pictured here from left to right are:
- Cassini terrestrial 8.5-inch MOVA Globe, MOVA International, San Diego: 2016; Made using images of original 1790 Cassini terrestrial globe gores from the David Rumsey Map Collection.
- Moon 6-inch MOVA Globe, MOVA International, San Diego: 2016
- Jupiter 4.5-inch MOVA Globe, MOVA International, San Diego: 2016
- Venus 6-inch MOVA Globe, MOVA International, San Diego: 2016
- Cassini Celestial 8.5-inch MOVA Globe, MOVA International, San Diego: 2016: Made using images of original 1792 Cassini celestial globe gores from the David Rumsey Map Collection, the very same gores shown as the background image of this case.
Making globes from printed hand-colored paper gores as shown on the back wall of this case is an age old method used to make most of the globes in this exhibition. But the five rotating MOVA globes displayed here employ modern printing methods that apply the information directly to the globe surface without using paper. Rotation occurs when light penetrates the globe surface, activating an internal solar cell. MOVA describes this system thus: “a sophisticated motion mechanism, powered by ambient light, rests discreetly inside each globe. Consisting of solar cells, magnetic elements and other proprietary components, the mechanism drives the continuous rotation without any batteries or power cords.”
In addition to these five MOVA globes, nineteen MOVA globes of various sizes are displayed in the Rumsey Map Center.
