The word “barometer” in literature has been used with great versatility, serving both as a precise scientific tool and a rich metaphorical device. On one hand, many authors—especially within adventure and science fiction genres—use detailed readings of the barometer to convey physical measurements and impending atmospheric changes, as seen in Jules Verne’s works ([1], [2], [3], [4], [5]) and Edgar Allan Poe’s descriptions of soaring altitudes ([6], [7], [8], [9]). On the other hand, writers like James Joyce ([10], [11]) and Edith Wharton ([12]) extend its significance to characterize individuals whose moods or intuitions function as a “barometer” for events, while even foundational texts such as Thomas Jefferson’s reference the term in a technical context ([13], [14], [15]). Thus, across diverse literary landscapes—from detailing navigational challenges to symbolizing the measurement of human emotion—the barometer remains a multifaceted emblem linking the empirical world with deeper, metaphorical insights.
