  • Christiaan Huygens, Horologium Oscillatorium … (Paris, France: F. Muguet, 1673), pages 18–19. From page 18: " … illudque accidit memoratu dignum, … brevi tempore reduceret." ( … and it is worth mentioning, since with two clocks constructed in this form and which we suspend in like manner, truly the cross beam is assigned two fulcrums [i.e., two pendulum clocks were suspended from the same wooden beam]; the motions of the pendulums thus share the opposite swings between the two [clocks], since the two clocks at no time move even a small distance, and the sound of both can be heard clearly together always: for if the innermost part [of one of the clocks] is disturbed with a little help, it will have been restored in a short time by the clocks themselves.)
