In the Middle Ages, Virgil's reputation was such that it inspired legends associating him with magic and prophecy. From at least the 3rd century, Christian thinkers interpreted Eclogues 4, which describes the birth of a boy ushering in a golden age, as a prediction of Jesus' birth. As such, Virgil came to be seen on a similar level as the Hebrew prophets of the Bible as one who had heralded Christianity.
