The word oculus serves as a versatile and resonant symbol in literary texts, evoking both the literal sense of the eye and a deeper metaphor for perception and insight. In some works, it straightforwardly denotes physical vision, as seen in architectural descriptions that highlight its circular form atop domes ([1], [2], [3]), while in other writings it becomes emblematic of inner awareness and moral discernment—its use in proverbial phrases underscores qualities like good reputation and faith ([4]). Moreover, oculus functions as a poetic device that bridges sensory perception with intellectual clarity, capturing a kind of enchanted or divinely inspired sight in lines such as “Nescio quis teneros oculus mihi fascinat agnos” ([5], [6], [7]). This layered symbolism, acknowledged in both classical discussions of language and later scholarly or satirical works ([8], [9]), illustrates how the term retains its richness and adaptability across differing literary landscapes.
