Description: | Cast copper alloy sub-triangular gnomon from a windowsill or small pedestal sundial. Chamfered straight oblique upper edge, notched and shaped curvilinear vertical edge, with two slight extensions forming integral tenons on the base, by which means it would have been permanently attached to the dial-plate. The gnomon angle is between 53.0 and 53.5 degrees indicating that it was designed for a latitude a little to the north of Norwich but, given the level of accuracy to which it was made, a location near to where it was found seems most likely.The profiled shape of the vertical edge suggests a late 16th -17th century date. Height 47mm. Length 43mm. 2mm thick.
