caption_attribution_description: English: Drawing of pendulum clock designed by Galileo Galilei around 1641. Part of the front supporting plate is removed by the artist to show the wheelwork. Although the source says the drawing is 'by' Galileo, it is undoubtedly the one drawn by his student Vincenzo Viviani in 1659, since Galileo was blind by the time he had the idea. Probably the first design for a pendulum clock, it was partly constructed by Galileo's son, who died before he could finish it. For more information see Al Van Helden (1995), Pendulum Clock, The Galileo Project. Alterations to image: none.
context_page_description: A pendulum clock is a clock that uses a pendulum, a swinging weight, as its timekeeping element. It was invented in 1656 by Christiaan Huygens. From the year 1656 until the 1930s, the pendulum clock was the world's most accurate way of keeping time. This is what caused it to be used by a lot of people all over the place.
