In literature, the word “variety” is employed in a remarkably flexible manner. In some works it categorizes and distinguishes tangible differences, as when various species, designs, or classifications are noted—ranging from heraldic beasts [1] and a spectrum of fish [2] to specific botanical or zoological types [3, 4]. At the same time, “variety” often functions metaphorically to evoke the richness and diversity of life, ideas, or artistic expression, as suggested in discussions of the interplay between light and shadow in life [5] or the endless nuances of perception [6]. Moreover, authors use the term to comment on the balance between diversity and uniformity, as seen in both the arts and social phenomena [7, 8], while even historical narratives employ it to describe cruel diversities of execution or the multifaceted character of societal actions [9]. This semantic versatility underscores how “variety” becomes a critical tool in literature to express both the complexity of concrete classifications and the more abstract diversity of human experience.
