In literature, the word vestal is often invoked to convey a sense of sacred purity and disciplined reserve. Historically, vestal refers to the Roman priestesses charged with tending the eternal flame—a symbol of both religious devotion and severe consequence for moral lapses ([1], [2], [3]). At the same time, many authors adopt vestal in a more metaphorical sense to describe characters or states of mind that embody an almost otherworldly, austere dignity, sometimes even tinged with irony or vulnerability ([4], [5], [6]). This dual usage allows writers across different eras to evoke the weight of ancient ritual while also commenting on the tensions between social expectations and personal desire ([7], [8]).
