1596, Artist: Christoph Margraf
The Rolling-Ball Clock: Invented for Emperor Rudolf II
The court clockmaker Christoph Margraf invented the rolling-ball clockwork, which featured a new principle of timekeeping. A ball runs down a slope between two wires, sets a second ball in motion, and then is raised back to its initial position. A counting mechanism transfers the information to a clock face. The three such clocks that have been preserved are mounted in cases with reflecting mirrors and scenery.
