Description: | Walter Hayes att Ye crosse daggers in moorefeilds londini fecit
Universal equinoctial ring dial for latitudes 0�-90� North. Standard dial (see related terms) except for the following details:-
The dial is for northern latitudes only. The bracket moves in the grooved rim of the meridian ring, on which is a latitude scale. The obverse side of the equinoctial ring is plain and the reverse and inner-rim both have hour scales. There is also a date scale. On the obverse side of the meridian ring, it is signed 'Walter Hayes att Ye crosse daggers in moorefeilds londini fecit'. Walter Hayes was one of the earliest makers to dispense with the table of latitudes and include an altitude quadrant in its place. This change was first mentioned in John Seller's 'Practical Navigation' (1672).
For more information regarding this dial please refer to the OUP & NMM catalogue, 'Sundials at Greenwich'.
