The Roman History · Amm. 23.6.24

This, however, as we have already related, was stormed by the generals of Verus Cæsar, who carried the image of the Cumæan Apollo to Rome, and placed it in the temple of the Palatine Apollo, where it was formally dedicated to that god by his priests. But it is said that after this statue was carried off, and the city was burnt, the soldiers, searching the temple, found a narrow hole, and when this was opened in the hope of finding something of value in it, from some deep gulf which the secret science of the Chaldæans had closed up, issued a pestilence, loaded with the force of incurable disease, which in the time of Verus and Marcus Antoninus polluted the whole world from the borders of Persia to the Rhine and Gaul with contagion and death.
