FARQUHAR CELESTIAL NAVIGATION SPHERE FOR THE DEPARTMENT OF THE NAVY
Circa 1953, plaque to walnut base with serial number and date
Item # 002JKP15K
A beautifully preserved celestial armillary sphere developed by Farquhar in Philadelphia for the Department of the Navy, this model was used for classroom instruction during the 1950s and 1960s. The present model was produced in 1953 and retains its original plaque with the date of production and serial number.
Resting over a walnut base, the machined aluminum structure allows the manipulation of the outer sphere with its 1100+ naked-eye stars and constellations printed on acrylic, within which the sun can be moved to match the present position with a small knob. The map of the earth is projected onto the plastic inner sphere, this also movable to account for alignment.
An identical Farquhar model circa 1953 is held in the collection of the Mariners' Museum and Park (acc. no. 1953.0021.000001) with a full descriptive write-up.
Beyond the instructive nature of the device, it is a beautiful sculptural element with bright colors silk-screened on the acrylic, high-quality brushed aluminum machining and a beautiful walnut base. It presents a very fine geocentric representation of the observed universe, a perceived space that accurately allows both for timekeeping and navigation through the use of the device.
