Calendarium perpetuum

This perpetual calendar was made in Germany at the beginning of the 18th century and consists of two fire-gilt silver leaves, with four bone leaves in between. On one side is a perpetual calendar with a rotating disc, on which the days of the week are given with their astrological signs. The disc reads: 'calendarium perpetuum'. On the other side is a rotating disc indicating the 'unbeweglijche fest tag' (the most important holiday), the month, constellation, length of day and sunrise and sunset. Both rotating discs are decorated with engraved floral motifs. Above and below the discs is the silhouette of a pile of spears, bows, flags and other weaponry. The bone blades are written with an illegible text.
