Universal equinoctial ring dial

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

The main hour scale is on the equinoctial ring and there is also a scale on the inner rim. There is a date scale and the equinoxes are marked at 10 March and 12 September. The instrument is signed 'E Culpeper fecit'.

This is an extremely austere version of Culpeper's style. The bracket has been removed and replaced the wrong way round so that the latitude marker appears on the reverse.

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