In literature, "legion" serves as both a specific military designation and a metaphor for vast multitude. In historical narratives, it denotes organized military units whose precise structure and strength are pivotal to the unfolding of events, as seen when regiments are identified by their number or purpose, underscoring the discipline and might of ancient armies [1][2]. Yet beyond its literal sense, the word often appears as a symbol of overwhelming quantity or uncontrollable force, as when a speaker exclaims, "My name is Legion, for we are many" [3] or when a writer uses it hyperbolically to evoke a swarm of troubles or adversaries [4][5]. This dual use—a concrete military formation and an expansive metaphor—illustrates the term's enduring power to convey both order and chaos within literary themes.
