The term “decadence” in literature is used to evoke images of decline and cultural exhaustion, spanning physical, moral, and intellectual spheres. For instance, H. G. Wells illustrates a planet where even basic skills such as fire-making have been lost, symbolizing a regression of essential human capabilities [1]. Meanwhile, Nietzsche’s prolific references depict decadence as not merely decline but as an intricate process involving the erosion of philosophical vigor and the corruption of moral values—linking it to everything from the weakening of aesthetic and logical faculties [2, 3, 4] to the eventual, almost necessary, condition of cultural life [5, 6]. Other authors, such as Pushkin and Galdós, casually employ the term to comment on the fading popularity or vitality of societal norms and traditions [7, 8]. In sum, decadence is rendered in literature as a multifaceted symbol of deterioration, reflecting the anxieties and transformations inherent in the fall of a civilization.
