The passage discusses the evolution of timekeeping from natural celestial indicators, like the sun and moon, to mechanical clocks. Initially, these natural rhythms guided human activity, while later mechanical timepieces refined the concept of time. In the 17th century, tall case clocks began incorporating a representation of the lunar cycle to assist with fishing and nighttime travel, utilizing a simple mechanism with a rotating disk that displayed two moons. However, this mechanism does not accurately depict the moon's phases due to its flawed representation of
