Universal equinoctial ring dial for latitudes 0˚-90˚ north
The dial is for northern latitudes only. The slider is spherical and the degree scale on the meridian ring is divided clockwise [0˚]-[90˚]. The remainder of the obverse and the reverse sides are filled with a table of latitudes for places in Europe named in Latin, including: 'Venetig (Venice) 45', 'Amstelodamum (Amsterdam) 52' and 'Londinum (London) 52'. There is also an hour scale on the reverse side and inner-rim of the equinoctial ring. Date and zodiac scales are also displayed, but there is no declination scale. The Equinoxes are marked at 20 March and 19 September. The dial has rather crude decoration on its gnomon, stops, bridge ends and supports.
