Summary
| Description |
English:
The first pendulum clock, invented by Dutch physicist
Christiaan Huygens
in 1657, and built by clockmaker Saloman Coster. This drawing is from Huygens' 1658 treatise on the clock,
Horologium
. The pendulum was driven by a
verge escapement
mechanism, so it had a very wide angle of swing compared to modern clocks, perhaps 80° to 90°. The clock was weight-driven, using an ingenious arrangement of two weights linked by a loop of cord. In order to "wind" the clock, the larger weight was simply lifted to the top. Alterations to image: removed caption.
