Cumaean Sibyl
In the Middle Ages, both the Cumaean Sibyl and Virgil were considered prophets of the birth of Christ, because the fourth of Virgil's "Eclogues" appears to contain a Messianic prophecy by the Sibyl. In it, she foretells the coming of a saviour, whom Christians identified as Jesus. This was identified by early Christians as such—one reason why Dante Alighieri later chose Virgil as his guide through the underworld in the "Divine Comedy". Similarly, Michelangelo prominently featured the Cumaean Sibyl in the Sistine Chapel among the Old Testament prophets, as had earlier works such as the Tree of Jesse miniature in the Ingeberg Psalter (c. 1210).
