Description:
This brass universal equinoctial ring dial consists of a meridian ring, hour ring, rotating crosspiece or bridge, and sliding suspension ring/handle. The meridian ring is calibrated on one side from 0 to 90 by single degree. The hour ring is calibrated on one side from I to XII twice. Half-hour divisions are along the inside edge of the hour ring. The bridge contains a sliding pinhole gnomon. The gnomon slides within a calendar scale calibrated and lettered by month on one side and scales from 20 to 0 to 20 and from 0 to 20 on the opposite side (declination scales). Both sides of the meridian ring and the verso of the hour ring are engraved with a list of forty-five European towns and latitudes, the majority being English. Henry Sutton (d. 1665) was a London instrument maker with numerous apprentices.
