The pendulum serves as an evocative symbol in literature, representing both the relentless march of time and the oscillation of human experience. In many works, it is portrayed as a literal mechanism—Chékov’s description of the clock that “exists to swing its pendulum and chime” ([1]) and its use in scientific demonstrations by figures like Jefferson ([2], [3], [4], [5]) underscore its role as an accurate, time-measuring device. Beyond its technical implications, authors like Bernard Shaw and Arthur Schopenhauer employ the pendulum metaphorically to illustrate the cyclical nature of history and the ambivalence inherent in life, suggesting that “an epoch is but a swing of the pendulum” ([6]) or that existence swings “backwards and forwards between pain and ennui” ([7]). In the eerie narratives of Edgar Allan Poe, the pendulum takes on a more sinister role, its measured oscillations contributing to an atmosphere of impending doom and psychological tension ([8], [9], [10]). Thus, whether as an instrument of science or a symbol of eternal recurrence, the pendulum richly encapsulates themes of time, change, and the human condition.
