Publius Vergilius Maro, better known as Virgil, was a Roman poet "best known for three major works—the Bucolics (or Eclogues), the Georgics, and the Aeneid." He is a man that both Dante-Poet and Dante-Pilgrim both look up to and he is Dante-Pilgrim's guide throughout the story. He takes Dante-Pilgrim through the different levels of hell and explains to him how each level is set up. He tells Dante that he was sent to him because Dantes love, Beatrice, was concerned for him. https://www.poetryfoundation.org/poets/virgil
