Universal equinoctial armillary dial
Universal equinoctial armillary dial for latitudes 0â”œÃ—_-90â”œÃ—_ north. The base is supported by three levelling screws and features a zodiacal scale and a date scale. Within these scales, the circular plate supporting the dial is free to rotate. At the centre of the plate is a compass. The four legs of the dial support, set on the circular plate, meet above the compass. Two opposite ones have metal pointers riveted to the circular plate at their base, which move over the date scale. These legs carry the meridian scale for setting the latitude.
