The term "fathom" has long served as a linguistic bridge between the concrete and the abstract. In its original sense as a unit of measurement, it appears in nautical contexts—for example, when explorers measure a river’s depth or describe the sea's vastness [1, 2, 3]. Over time, however, authors have skillfully employed it as a metaphor for understanding, using expressions like “Could any one fathom the cruelty beneath that fair exterior?” [4] and Socrates’ self-reference to his quest “to fathom all things” [5]. In a playful twist, the name Fathom also becomes a character in Smollett’s adventures, illustrating a personification that enriches narrative style [6, 7, 8]. Thus, whether indicating literal depth or the limits of human insight, "fathom" encapsulates a dual meaning that has fascinated writers across both adventurous and philosophical literature.
