Publius Vergilius Maro, commonly known as Virgil, was a prominent Roman poet who lived from 70 BCE to 19 BCE. He is best known for his epic poem, the 'Aeneid', which tells the story of Aeneas, a Trojan hero who travels to Italy and becomes an ancestor of the Romans. Virgil's work not only reflects the cultural values of ancient Rome but also played a significant role in shaping Latin literature and influencing later European literary traditions.
