Pendulum from Reproduction of Huygens Clock Movement
Record status
Individual type · partial
Period
1927
This clock pendulum, catalogued as object number 1927-1981 Pt1/1, was produced in 1927 by J. Morrison & Sons in London as part of a reproduction of Christiaan Huygens's 1673 clock movement described in Horologium Oscillatorium.
The component is preserved in the Science Museum Group Collection as a part of the larger clock reproduction assembly 1927-1981 Pt1. The pendulum comprises a straight, slender rod terminating in a curved, transverse pendulum bob at the lower end, along with an upper sliding brass weight with a thumbscrew fitting near the suspension end.

- • Slender, straight metallic pendulum rod • Curved, crescent-like transverse pendulum bob attached at the bottom • Museum accession number marked on the surface of the lower curved bob • Small brass auxiliary weight or collar with thumbscrew positioned along the upper section of the rod • Flattened or shaped suspension terminal at the upper tip
- Physical Description
- The component is described as a slender, straight metallic pendulum rod with a curved, crescent-like transverse pendulum bob attached at the bottom. A small brass auxiliary weight or collar featuring a thumbscrew is positioned along the upper section of the rod, which terminates in a flattened or shaped suspension terminal. The museum accession number is marked on the surface of the lower curved bob.
- Historical Design Notes
- The reproduction timepiece differs from that illustrated in Huygens's 1658 work, 'Horologium', regarding the method of pendulum suspension. The pendulum is hung between cycloidal 'cheeks' to demonstrate Huygens's calculations concerning the period of a pendulum's arc.
- Object Identity and Context
- This component is identified as a pendulum (accession number 1927-1981 Pt1/1), part of a 1927 reproduction of Christiaan Huygens's 1673 clock movement, 'Horologium Oscillatorium', constructed by J. Morrison & Sons of London. The pendulum is catalogued as a component of the larger reproduction assembly 1927-1981 Pt1.
