Trōiae, or Troy, refers to the ancient city that was the setting of the legendary Trojan War, a central theme in epic literature, particularly in the context of Vergil's 'Aeneid.' In the Aeneid, Trōiae symbolizes both a fallen civilization and a point of departure for Aeneas, the protagonist, as he embarks on a journey to found a new homeland in Italy. The city represents not only the struggles and losses associated with war but also the idea of destiny and the divine intervention that shapes Aeneas's fate.
