This prediction was verified before many years in the invasion of the Gauls and the destruction of Rome,—a tale which we have next to tell.
Camillus, finding that Veii was not to be taken by assault over its walls, began to approach it from below. Men were set to dig an underground tunnel, which should pass beneath the walls, and come to the surface again in the Temple of Juno, which stood in the citadel of Veii. Night and day they worked, and the tunnel was in course of time completed, though the ground was not opened at its inner extremity.
Then many Romans came to the camp through desire to have a share in the spoil of Veii. A tenth part of this spoil was vowed by Camillus to Apollo, in reward for his oracle; and the dictator also prayed to Juno, the goddess of Veii, begging her to desert this city and follow the Romans home, where a temple worthy of her dignity should be built.
All being ready, a fierce assault was made on the city from every side. The defenders ran to the walls to repel their foes, and the fight went vigorously on. While it continued the king of Veii repaired to the Temple of Juno, where he offered a sacrifice for the deliverance of the city. The prophet who stood by, on seeing the sacrifice, said, "This is an accepted offering. There is victory for him who offers the entrails of this victim upon the altar."
The Romans who were in the secret passage below heard these words. Instantly the earth was heaved up above them, and they sprang, arms in hand, from the tunnel. The entrails were snatched from the hands of those who were sacrificing, and Camillus, the Roman dictator, not the Veientian king, offered them upon the altar. While he did so his followers rushed from the citadel into the streets, flung open the city gates, and let in their comrades. Thus both from within and without the army broke into the town, and Veii was taken and sacked.
From the height of the citadel Camillus looked down upon the havoc in the city streets, and said in pride of heart, "What man's fortune was ever so great as mine?" But instantly the thought came to him how little a thing can bring the highest fortune down to the lowest, and he prayed that if some evil should befall him or his country it might be light.
As he prayed he veiled his head, according to the Roman custom, and turned toward the right. In doing so his foot slipped, and he fell upon his back on the ground. "The gods have heard my prayer," he said. "For the great fortune of my victory over Veii they have sent me only this little evil."
He then bade some young men, chosen from the whole army, to wash themselves in pure water, and clothe themselves in white, so that there would be about them no stain or sign of blood. This done, they entered the Temple of Juno, bowing low, and taking care not to touch the statue of the goddess, which only the priest could touch. They asked the goddess whether it was her pleasure to go with them to Rome.
Then a wonder happened; from the mouth of the image came the words "I will go." And when they now touched it, it moved of its own accord. It was carried to Rome, where a temple was built and consecrated to Juno on the Aventine Hill.
