I am interested in a pedestal dial in the English Lake District. My interest is in the arrangement for finding the azimuth of the sun. The dial is by Richard Whitehead, dated 1688, and a central compass rose is divided into points, the points being further divided into one eighths i.e. better than 1.5 degrees. The gnomon is vertically drilled for a central shadow pin, which is missing.
Does anyone have any information about shadow pins in sundials and are there other examples of dials centrally inscribed in points with the object of finding the sun's direction. And were points an essentially nautical feature?
The dial was first listed in the BSS Sundial Register, No, 2222 in Cumbria, by Robert Sylvester.
