A New Portable Orrery
This orrery consists of a wooden circular baseboard with engraved paper pasted on top and has tellurium and planetarium attachments. The basedboard has calendar and zodiac scales and indicates the equinoxes, solstices and seasons. At the centre images of the planets are engraved in order to indicate their relative sizes. This series includes Geordium Sidus, later known as Uranus, thus dating the orrery to post-1781. In this area we also find the text "A NEW PORTABLE ORRERY. Invented and made by W. JONES, and sold by him in Holborn, LONDON." A comet, probably Halley's Comet, is also depicted.
The tellurium attachment demonstrates the annual and diurnal motions of the Earth and the motion of the Moon around the Earth, with gears moved by a brass bar. The Sun, Moon, gears and brackets are all brass while the Earth and knob opposite the bar are ivory. A brass plate below the Earth is covered by a paper scale that shows the phases of the Moon and a paper scale covering a brass circle shows the zodiac.
