The term "blas" appears in literature in multiple nuanced ways. As an adjective, "blasé" is often employed to describe a state of indifferent sophistication or emotional detachment, as seen in characters from F. Scott Fitzgerald’s works ([1], [2], [3]) and even amongst professional detectives in Arthur Conan Doyle’s narrative ([4]). In contrast, "Ruy Blas" emerges as a proper noun—a title rich with dramatic and critical connotations in works addressing political intrigue and social commentary, such as in texts by Victor Hugo and his correspondents ([5], [6], [7], [8]). Additionally, the motif of "Gil Blas" recurs, functioning not only as a literary reference but also as the name of a periodical or narrative space in Guy de Maupassant's stories ([9], [10], [11], [12]). Thus, throughout various periods and genres, "blas" and its variants have embodied both an emotional attitude of weariness and served as a symbolic reference to influential literary works and cultural critique.
