The word “cardinal” serves multiple narrative functions in literature, frequently denoting a high-ranking ecclesiastical figure whose presence influences the political and moral landscape. In historical and adventure works, the cardinal often emerges as a figure of authority—commanding military ventures [1], instilling an air of dignified mystery at his entrance [2] or even provoking trepidation with his calculated silence [3]. At the same time, some authors extend its meaning beyond a mere title, evoking ideas of primacy and foundational virtue, as seen when the term is juxtaposed with moral absolutes or fundamental numbering systems [4][5]. Thus, whether as an emblem of institutional power or as a metaphor for essential principles, “cardinal” enriches both character and theme across a spectrum of literary narratives [6][7].
