Upon their departure, Vindicius secretly quitted the house, but was at a loss what to do in the matter, for to arraign the sons before the father Brutus, or the nephews before the uncle Collatinus, seemed equally (as indeed it was) shocking; yet he knew no private Roman to whom he could intrust secrets of such importance. Unable, however, to keep silence, and burdened with his knowledge, he went and addressed himself to Valerius, whose known freedom and kindness of temper were an inducement; as he was a person to whom the needy had easy access, and who never shut his gates against the petitions or indigences of humble people. But when Vindicius came and made a complete discovery to him, his brother Marcus and his own wife being present, Valerius was struck with amazement, and by no means would dismiss the discoverer, but confined him to the room, and placed his wife as a guard to the door, sending his brother in the interim to beset the king's palace, and seize, if possible, the writings there, and secure the domestics, whilst he, with his constant attendance of clients and friends, and a great retinue of attendants, repaired to the house of the Aquillii, who were, as it chanced, absent from home; and so, forcing an entrance through the gates, they lit upon the letters then lying in the lodgings of the ambassadors. Meantime the Aquillii returned in all haste, and, coming to blows about the gate, endeavoured a recovery of the letters. The other party made a resistance, and throwing their gowns around their opponents' necks, at last, after much struggling on both sides, made their way with them their prisoners through the streets into the forum. The like engagement happened about the king's palace, where Marcus seized some other letters which it was designed should be conveyed away in the goods, and, laying hands on such of the king's people as he could find, dragged them also into the forum. When the consuls had quieted the tumult, Vindicius was brought out by the orders of Valerius, and the accusation stated, and the letters were opened, to which the traitors could make no plea. Most of the people standing mute and sorrowful, some only, out of kindness to Brutus, mentioning banishment, the tears of Collatinus, attended with Valerius's silence, gave some hopes of mercy. But Brutus, calling his two sons by their names, "Canst not thou," said he, "O Titus, or thou, Tiberius, make any defence against the indictment?" The question being thrice proposed, and no reply made, he turned himself to the lictors and cried, "What remains is your duty." They immediately seized the youths, and, stripping them of their clothes, bound their hands behind them and scourged their bodies with their rods; too tragical a scene for others to look at; Brutus, however, is said not to have turned aside his face, nor allowed the least glance of pity to soften and smooth his aspect of rigour and austerity, but sternly watched his children suffer, even till the lictors, extending them on the ground, cut off their heads with an axe; then departed, committing the rest to the judgment of his colleague. An action truly open alike to the highest commendation and the strongest censure; for either the greatness of his virtue raised him above the impressions of sorrow, or the extravagance of his misery took away all sense of it; but neither seemed common, or the result of humanity, but either divine or brutish. Yet it is more reasonable that our judgment should yield to his reputation, than that his merit should suffer detraction by the weakness of our judgment; in the Roman's opinion, Brutus did a greater work in the establishment of the government than Romulus in the foundation of the city.
Upon Brutus's departure out of the forum, consternation, horror, and silence for some time possessed all that reflected on what was done;the easiness and tardiness, however, of Collatinus gave confidence to the Aquillii to request some time to answer their charge, and that Vindicius, their servant, should be remitted into their hands, and no longer harboured amongst their accusers. The consul seemed inclined to their proposal, and was proceeding to dissolve the assembly; but Valerius would not suffer Vindicius, who was surrounded by his people, to be surrendered, nor the meeting to withdraw without punishing the traitors; and at length laid violent hands upon the Aquillii, and, calling Brutus to his assistance, exclaimed against the unreasonable course of Collatinus, to impose upon his colleague the necessity of taking away the lives of his own sons, and yet have thoughts of gratifying some women with the lives of traitors and public enemies. Collatinus, displeased at this, and commanding Vindicius to be taken away, the lictors made their way through the crowd and seized their man, and struck all who endeavoured a rescue. Valerius's friends headed the resistance, and the people cried out for Brutus, who, returning, on silence being made, told them he had been competent to pass sentence by himself upon his own sons, but left the rest to the suffrages of the free citizens: "Let every man speak that wishes, and persuade whom he can." But there was no need of oratory, for, it being referred to the vote, they were returned condemned by all the suffrages, and were accordingly beheaded.
