A New Portable Orrery

This orrery has a single wooden circular baseboard with two different attachments: a tellurium and a planetarium. The Earth and finger knob are ivory.The base has engraved paper on the top surface, which includes the inscription "A New Portable Orrery. Invented and made by W. Jones and sold by him in Holborn, London'. The printed base paper is the same as on AST1060 and AST1062, and includes scales of calendar, seasons and zodiac, the orbit of a comet (possibly Halley's Comet) and the relative sizes of the seven known planets. The object's dating is determined by the inclusion of Uranus (or Geordium Sidus), discovered in 1781.

The tellurium attachment, designed to demonstrate the relative positions and motions of the Sun, Earth and Moon, is scratched and incomplete, with the Sun, Moon, finger bar and several brackets are missing. The Earth and the finger knob are ivory, and the plate under the Earth is covered in printed paper showing the Moon's phases. A brass ring, also covered in paper, shows the zodiac. There may have originally been a lamp, but this is now missing. The base and tellurium are contained in an original, fitted wooden box.

The planetarium attachment is in a seperate box and has six brass brackets for the planets. The planets (Mercury, Earth and Moon, Mars, Jupiter with 4 satellites and Saturn with a broken ring and 5 satellites) are in ivory. There is also a small semicircular brass fixing, which may have once been attached to the Earth model in the tellurium.
