Galileo’s Pendulum Clock Design Replica

This is a replica of Galileo's design for a pendulum clock. In 1642, for a Dutch longitude prize, Galileo proposed both an astronomical solution and an accurate sea clock—the first clock ever to have a pendulum. Galileo died before making the clock, but his son built a model in 1649.
