BRITISH REFLECTING CIRCLE

By Thomas Jones (British, fl. 1806-1861). Signed on frame "Thomas Jones 62 Charing Cross London". Lattice framed brass reflecting circle with inset silver scale, triple arms with silvered verniers, adjustable with tangential screw, magnifier, sighting scope with two lenses, colored glass filters and mahogany grip. Original mahogany case.

  • Provenance:
    Sotheby's, London, February 1986.
    The Kelton Collection of Marine Art & Artifacts.
  • Exhibited:
    Pacific Asia Museum at U.S.C., Trade and Treasure Exhibition, 1987.

    Notes:
    Thomas Jones studied with Jesse Ramsden, the preeminent English instrument maker of his time, and married his daughter. The reflecting circle was devised in the 1750s by German astronomer Tobias Mayer in order to measure wider angles through the use of a circle of 360 degrees instead of the arc of 120 degrees as in the sextant.
