A fine and very rare early 17th century spring driven, quarter striking, ebony rolling ball clock Johann Sayller, Ulm, c1630 The rectangular case with a hinged lid framed by delicate ripple mouldings to the edge and shaped panel to the centre, the two longer side panels similarly decorated, the rear glazed to offer inspection of the movement, the front set with the dial, each corner applied with a turned three-quarter column on a pedestal, raised on a moulded base on turned and ringed feet, the interior lined with gilt tooled paper, the front panel set with the gilt bezel framing the 4 and 5/8ths of an inch diameter silvered dial, the outer minute band with alternate shaded minute numerals, each five and each quarter marked in Arabic and Roman numerals respectively, the inner track of Roman hours simply engraved with 'club' shaped half hour markers to a plain centre, with a gilt hour and a blued steel minute hand, the main going-train set within a pair of steel plates measuring 6 inches by 7 1/8th of an inch united by square section steel rods secured at each end by square nuts, the spring barrel of brass with steel endcaps to a slender fusee (each 3.75 inches long) driving a 5 inch diameter great wheel, large centre/pin -wheel , third wheel and four-vane fly, the centre arbor protrudes through the 'frontplate ' of the movement and terminates in a five leaf brass pinion driving an arbor through 90 degrees to drive the motion work behind the dial, each arbor set in a brass bush, the hour and quarter striking trains driven by a pair of spring barrels mounted within smaller brass plates and wound from the side, each with a solid countwheel activating a steel hammer and bell in the base. Opening the lid reveals the painted panel framed by shaped gilt edges mounted with eight hooped brackets carrying the wire line to offer a total track length of approximately 1.75 metres (5ft 9ins), as the ball reaches the end of its travel, it drops through a hole to run along a track where it is picked up by a counter weighted, pivoted hopper which returns the ball to the top of the track. The case 31cms (12ins) wide, 36cms (14.25ins) deep and 28cms (11ins) high. Fußnoten Exhibited: Innovation and Collaboration; The early development of the pendulum clock in London, Bonhams New Bond Street, September 2018. Exhibit number 8. The first patent for a rolling ball clock was taken out in 1595 by Christof Margaf of Vienna. Others are known by Christolph Rohr of Leipzig, and Hans Schlottheim of Augsburg. Literature: Maurice, Raderuhr, 1976, p.82, pl.645. The panel is taken from Jacques Callot (1592-1635) for the volume Sacra Cosmologia ou Le titre aux astrologues, circa 1630 and shows five astronomers within a landscape; image kindly reproduced with the permission of Princeton University Art Museum.
