John Harrison’s grasshopper escapement

Target entity: John Harrison’s grasshopper escapement
Context triple: [Corpus Clock, inspiration, John Harrison’s grasshopper escapement]

• A. Schickard calculating clock
  The Schickard calculating clock was an early 17th-century mechanical calculator designed by Wilhelm Schickard, often regarded as one of the first known attempts to build an automatic computing machine.
• B. Horologium Oscillatorium
  Horologium Oscillatorium is a landmark 1673 treatise by Christiaan Huygens that laid the foundations of pendulum clock theory and classical mechanics, including an early formulation of the laws of motion and the tautochrone problem.
• C. Larcum Kendall K1 chronometer
  The Larcum Kendall K1 chronometer was an 18th-century marine timekeeper, closely modeled on John Harrison’s H4, that famously demonstrated the practicality of accurate longitude determination at sea.
• D. Hampton Court astronomical clock
  The Hampton Court astronomical clock is a 16th-century Renaissance clock at Hampton Court Palace that displays the time alongside astronomical information such as the phases of the moon and the movement of the sun.
• E. Chronometer
  Chronometer is an experimental 1971 electronic composition by Harrison Birtwistle that explores complex rhythmic structures using recorded clock sounds.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Target entity: John Harrison’s grasshopper escapement
Target entity description: John Harrison’s grasshopper escapement is a low-friction clock escapement mechanism invented in the 18th century that significantly improved the accuracy and reliability of timekeeping.
