The outer part of the lid of this dial has an hour circle numbered from 1 to 12 twice, is decorated with arabesques in the spandrel spaces and bears the inscription on two borders 'VIGILATE QVIA NESCITIS DIEM NEQVE HORAM MAT 25' ('Be alert, because you don't know the hour nor the day, Matthew 25'). The inner side has a table of latitudes. The box contains a compass with eight directions named and arabesques in the spandrels.
