In the 1500s, priceless knowledge was validated through splendid casework. Supporting technological endeavor was a way for noble sponsors to earn intellectual kudos, even to magically gain scientific knowledge as if by osmosis. Holy Roman Emperor Ferdinand I, for example, famously filled his curiosity cabinet with clocks. This example shows the stars’ positions, days of the week with planetary rulers, the time in Roman and Arabic numerals, daylight and nighttime hours, and the date; it even includes a disk for setting an alarm. Its Viennese maker, Behaim, may have collaborated with Metzger, of Augsburg, whose clocks were so sought after that he stretched guild rules to meet the demand.
