There, when at Cumae landing from the main, / Avernus' lakes and sounding woods ye gain, / thyself shalt see, within her rock-hewn shrine, / the frenzied prophetess, whose mystic strain / expounds the Fates, to leaves of trees consign / the notes and names that mark the oracles divine."

The oracle was fulfilled.
