When, accordingly, the youths had been persuaded and held conference with the Aquillii, it was decided that all the conspirators should swear a great and dreadful oath, pouring in libation the blood of a slain man, and touching his entrails. For this purpose they met at the house of the Aquillii.At the house of the Vitellii, according to Livy, ii. 4, 5. Now the room in which the ceremony was to be held was, as was natural, dark and somewhat desolate. Without their knowing it, therefore, a slave named Vindicius had concealed himself therein, not with design, or with any inkling of what was to happen there;

he merely chanced to be there, and when they came in with anxious haste, he was afraid to be seen by them, and hid himself behind a chest that lay there, so that he saw what they did, and heard what they resolved upon. Their decision was to kill the consuls, and when they had written letters to Tarquin to this effect, they gave them to his envoys, who were living there as guests of the Aquillii, and were then present at the conspiracy.

Their business transacted, the conspirators departed, and then Vindicius stole secretly away from the house. He knew not what use to make of what had befallen him, but was at a loss, considering it a dreadful thing, as it really was, to arraign the sons of Brutus before their father, or the nephews of Collatinus before their uncle, on the most abominable charges, and yet believing that no Roman in a private station could be entrusted with such important secrets.

The last thing that he could do, however, was to hold his peace, and driven on by his knowledge of the affair, he made his way somehow to Valerius, attracted especially by the affable and kindly ways of the man.Vindicius laid the matter before the consuls, according to Livy, ii. 4, 6. For he was easily accessible to all the needy, always kept open house, and never refused to hear or help one of the lowly.

Accordingly, when Vindicius came to him and told him the whole story, in the presence of his brother Marcus only, and of his wife, Valerius was struck with consternation and fear, and would not now let the man go, but shut him up in a room and set his own wife to guard the door. Then he ordered his brother to surround the royal residence, seize the letters, if possible, and take the servants into custody. He himself, with the numerous clients and friends who were always about him, and with a large company of retainers, went to the house of the Aquillii, who were not at home.
