Universal equinoctial ring dial

Universal equinoctial ring dial for all latitudes. Standard dial (see related terms) except for the following details:-

'S' and 'N' are marked either side of zero on the latitude scale. There are hour scales on both the obverse side and the inner rim of the equinoctial ring. There is a date scale, no zodiac scale and the equinoxes are marked at 10 March and 13 September.

This is a beautiful miniature dial by a master craftsman, but the size probably considerably reduced the practicality of this instrument. It is signed 'Edm. Culpeper fecit' on the obverse side of the meridian ring.

For more information regarding this dial please refer to the OUP & NMM catalogue, 'Sundials at Greenwich'.
