They're guilty by their own confessions
Of felony, and at the Sessions
Upon the bench I will so handle 'em,
That the vibration of this pendulum
Shall make all taylors' yards of one
Unanimous opinion;
A thing he long has vaunted of,
But now shall make it out of proof.
Hudibras was certainly written before 1663: ten years later Huyghens speaks of the idea of so employing the pendulum as a common one.
