Combination nocturnal and sundial. Several parts are missing. Comprises a disk with a hole at the center and fitted with a finely tooled handle. On both sides are 27 matching holes. A T-shaped brass strip is placed across the opening. The circumference carries protruding triangular tips. Engraved with the date (1560) and the word "Paschas," which is hard to interpret. Provenance: Medici collections.
