This gilded-brass case is covered in a complex arrangement of decoration and dials with functions for displaying the time, as well as calendrical and astronomical information. Designed as an opulent demonstration of its owner’s wealth and scientific knowledge, this clock is called a Metzger type after the Augsburg clockmaker Jeremias Metzger, who made other, similar pieces. Princely themes of hunting and the allegorical figures that weave around the dials reflect the well-rounded education of the Renaissance owner.
