Preliminary Assessment of a Pocket Sundial Excavated at Round Church Street, Cambridge, in the Summer of 2019

A portable diptych sundial made of animal bone, recovered during excavation in Cambridge, is assessed. It is estimated to be a 17th-century continental import, likely French or German, based on design flourishes and the latitude (48°) for which it was calculated. The dial uses a missing string gnomon and features a horizontal leaf with a compass box.
