Description
This circular horizontal pedestal sundial of bronze or brass has indicated on it the hours from V to XII to I to VII. The hour scale is divided to five minute intervals. It has three holes for screws to attach dial it to a pedestal, but no pedestal. The gnomon is at an angle of about 40 degrees. It is screwed to the dial plate for use, but kept separately for storage. A mark on the base reads: B. PIKE & SONS (/) 518 BROADWAY (/) NEW YORK (/) L 40 [symbol for degrees] 42'. New York City is at a latitude of 40 degrees, 44 minutes.
The company Benjamin Pike & Sons was at 518 Broadway from 1855 to 1867. An 1856 Pike catalog included advertised a horizontal sundial, but it is not identical to this one.
