In making Francesco believe that his strategy has worked, and that Zima’s advances have indeed been frustrated, Zima displays his superior intelligence. Francesco’s Wife may have obeyed his orders in letter, but her sighs mean that she disobeyed in spirit. But by letting Francesco believe in her obedience, Zima also adds a layer of protection to their eventual affair—Francesco will henceforth suspect nothing of the two, since he thinks his trust in his wife has been confirmed. The argument Francesco’s Wife has with herself illustrates the “carpe diem” or “seize the day” literary trope, where the advent of old age is used as an incentive to enjoy love in the present moment.
