mechanical timekeeping
The invention of the pendulum clock in the
was considered a major breakthrough in timekeeping because it was
than earlier mechanical clocks driven by weights, gears, and springs.
 
The pendulum clock worked on the principle that a pendulum of a given length takes nearly the
to complete each oscillation. This regular motion allowed the clock to measure time more precisely. Invented by
in
, the pendulum clock greatly improved the accuracy of
and remained one of the most reliable methods of measuring time for many years.
