Literary notes about span (AI summary)
The term "span" is employed with remarkable versatility in literature, functioning both as a measure of physical distance and a metaphor for time, life, or connection. In certain works, it denotes a tangible length, as when a lead effigy is shaped to be about a human hand’s span [1] or when the physical measurement of architecture is described by a single span of an arch [2]. In more abstract uses, authors refer to the span of human life to encapsulate its brevity or significance, as seen in lines that lament the limited span of existence [3] and explore its ephemeral nature [4]. Additionally, the word enriches idiomatic expressions that evoke pristine order, as in the phrase "spick and span" to describe something immaculate [5]. This dual capacity—as a marker of both spatial dimension and temporal or metaphorical interval—demonstrates just how adaptable and evocative "span" has been as a literary tool.
