Equinoctial Sundial
notes: label: Description
content: This brass equinoctial ring dial is an Indian instrument, probably from the late 17th or early 18th century. It consists of two brass rings with copper-colored joints and a brass rotating crosspiece. A semicircle of each ring is divided into 30 (outer ring) and 34 (inner ring) sections. The crosspiece is doubly divided into eight sections on one side and six sections on the other face. The side with six sections is not evenly divided. All of the markings on the instrument are in Sanskrit. The donor's appraiser believed that the style of Sanskrit placed the sundial in the Jaipur area. The dial came to NMAH with no support piece, but a brass and felt replica is now stored with the instrument. There is no suspension ring on this dial.
