The term “peninsula” in literature has been employed with both precision and evocative flair, serving as a geographical marker and a symbol of strategic, cultural, or mythical significance. In adventure narratives like those of Jules Verne, the peninsula marks critical landmarks—whether as the Indian Peninsula looming near Ceylon ([1]) or the tip disappearing below the horizon as a beacon for further exploration ([2], [3], [4]). Historians and geographers, notably Strabo, use the term rigorously, cataloging peninsulas with detailed descriptions of their shape and the nations that inhabit or contest them ([5], [6], [7]). At the same time, in military and political accounts, a peninsula is presented as a natural bastion, offering both defensive advantage and symbolic meaning in territorial discourse ([8], [9], [10]). Even in more metaphorical or culturally inflected passages, such as those by Frazer or Darwin, the word extends beyond its physical attributes to evoke broader associations of isolation, uniqueness, or historical continuity ([11], [12]). This diverse usage underscores the term’s rich capacity to bridge concrete geography with abstract ideas across genres and eras.
