Writers have long employed “atrabilious” to evoke a sense of bitterness, gloom, and ill temper in both characters and atmospheres. In one instance, it is used to describe a pessimistic, philosophically inclined group with a dark humor, reflecting the mood of an era steeped in somber introspection [1]. At other times, the term characterizes individuals defined by sallow features and a dour temperament that borders on the beastly, underscoring an inner turmoil and acerbic disposition [2, 3]. Moreover, some authors extend its reach into social or political commentary, using “atrabilious” to critique stances or temperaments that seem inherently obstinate or ill-natured, as in the depiction of a faction defined by its gloomy outlook [4]. This multifaceted term, therefore, serves as a powerful literary device to highlight both personal melancholy and a broader social pessimism.
