In literature, the term cognomen plays a versatile role that shifts with context and purpose. In historical texts, it often functions as a formal label that denotes familial branch or personal distinction, as seen when a freedman changes his cognomen to reflect his status ([1]) or when ancient figures carry names that underscore inherited honor ([2], [3]). In contrast, more contemporary writings use the cognomen as a creative or descriptive moniker, lending a character an added layer of identity or irony—consider the “Lisping Poet” ([4]) or a moniker that captures heroic or symbolic traits ([5]). This blend of historical gravitas and modern inventiveness enriches narratives by connecting characters to both their cultural pasts and the expressive potentials of language.
