What about a rock on a long lute string?  Vincenzo and
his sons (Michelangelo and Galileo Galilei) are said to 
have been dangling a lute string from the Leaning Tower 
of Pisa to test the tensile strength of lute
strings, when Galileo discovered the principle of the
pendulum. After his death, a proposal was found in bhis 
papers to use the pendulum principle marking time in 
music 200 years
before Maezel (who stole the idea for his metronome).
