Publius Vergilius Maro (October 15, 70 BC – September 21, 19 BC), later called Virgilius, and known in English as Virgil or Vergil, was a classical Roman poet, the author of the Eclogues, the Georgics and the substantially completed Aeneid, the last being an epic poem of twelve books that became the Roman Empire's national epic. A fictional depiction of Virgil was Dante Alighieri's guide through hell and purgatory in Dante's epic poem The Divine Comedy.
