Summary

Description
Drawing of the first pendulum clock, designed by Dutch scientist Christiaan Huygens in 1657. Huygens contracted his clock designs to clockmaker Salomon Coster of The Hague, who actually built the clock. The pendulum had a wider swing than modern clocks, perhaps 80°-100°, due to its verge escapement. The drive force for the clock was provided by the two weights at bottom in an ingenious "endless rope" mechanism.
