Description: | A Post Medieval copper alloy dial from a pocket sun dial (late 16th - early 17th century). The dial has a circular frame, two internal projecting tabs to which are tethered each side of a folding triangular fin - the gnomon. Inscribed around the edge of the frame are the numbers 5-12 and 1-7 which represent the hours of daylight for the northern latitude. When raised the gnomon would have cast a shadow to enable the user to tell the time. The case to house this dial is missing. There are no visible maker's marks but it is likely to have been made in Nuremburg.Dimensions: Diameter: 15.88mm; thickness of frame: 0.82mm; thickness of dial when the gnomon is raised: 9.04mm; thickness of dial when the gnomon is lowered: 3.30mm; weight: 0.77g.Identification by Hazel Forsyth, Senior Post Medieval Curator, Museum of London.
