Virgil, wearing a toga and holding a scroll on his lap is attended by two Muses; Clio (history), stands on his left holding a scroll. Melpomene (tragedy), stands to the right with a tragic mask. The scroll is open at Aeneid I, line II: :O Muse! the cause and the crimes relate, What Goddess was provoked, and whence her hate!" Publius Vergilius Maro (70-19 BC), usually called Virgil or Vergil in English, was an ancient Roman poet of the Augustan period. Virgil is ranked as one of Rome's greatest poets. His Aeneid has been considered the national epic of ancient Rome. Modeled after Homer's Iliad and Odyssey, the Aeneid follows the Trojan refugee Aeneas as he struggles to fulfill his destiny and arrive on the shores of Italy. According to the tradition, Virgil traveled to Greece around 19 BC in order to revise the Aeneid. While there he caught a fever and died in 19 BC. The mosaic, which dates from the 3rd Century AD, was discovered in Hadrumetum and is now on display in the Bardo Museum in Tunis.
