[edit] Summary

Description

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.
