Where did clocks come from?
By Rick Cook
For centuries men have tried to trace the origins of mechanical clocks, gear-driven and escapement controlled, without much success. While time keeping instruments go back to ancient Egypt, until the middle ages the devices were water driven or based on the length of time it took a candle to burn down. Then suddenly clockwork clocks with escapements and trains of gears appeared.

The answer to the mystery, Price says, is that we were looking in the wrong places. The birth and early development of clockwork was in scientific instruments such as planetariums, not in time keeping. After centuries of development in other fields, the principles were suddenly transferred to time-keeping mechanisms. One striking example of this alternate line of development is the Antikithera mechanism, a Hellenic mechanism for tracing the motions of the planets. Price shows similar examples from Hellenic times to the birth of true clocks in the 1300s. Along the way he traces the role of perpetual motion machines and the compass in the development of clocks.

A fascinating book
