The Tiburtine Sibyl or Albunea was a Roman sibyl, whose seat was the ancient Etruscan town of Tibur (modern Tivoli). The mythic meeting of Cæsar Augustus with the Sibyl, of whom he inquired whether he should be worshiped as a god, was often depicted by artists from the late Middle Ages onwards. In the versions known to the later Middle Ages, for example the account in the Golden Legend, Augustus asked the sibyl whether he should be worshipped as a god, as the Roman Senate had ordered. She replied by showing him a vision of a young woman with a baby boy, high in the sky, while a voice from the heavens said "This is the virgin who shall conceive the saviour of the world". The episode was regarded as a prefiguration of the Biblical Magi's visit to the new-born Jesus.
