Low-tech clock-making requires an unusual combination of talents. First, it calls for considerable practical skills; a clock is likely the most complex gadget in the clock-maker’s society. However, it is also bleeding-edge science, embodying physics and applied mathematics. However, many low-tech scholars disdain practical skills, and few craftsmen receive an academic education. A scholar might find other people to work from his designs, but this template assumes that the clock-maker does at least some of the building himself. Clocks are often built for ritual purposes (plotting horoscopes, scheduling religious services), so the template includes optional features appropriate to a priest, monk or astrologer.
