[5,28] After he had received the praises of the senators and obtained favourable omens for his enterprise, he crossed the river. And arriving at the camp of the Tyrrhenians, he entered it, having deceived the guard at the gates, who took him for one of their own countrymen since he carried no weapon openly and spoke the Tyrrhenian language, (p83) which he had been taught when a child by his nurse, who was a Tyrrhenian. When he came to the forum and to the general's tent, he perceived a man remarkable both for his stature and for his physical strength, clad in a purple robe and seated upon the general's tribunal with many armed men standing round him. And jumping to a false conclusion, as he had never seen the king of the Tyrrhenians, he took this man to be Porsena. But it seems he was the king's secretary, who sat upon the tribunal while numbering the soldiers and making a record of the pay due them. Making his way, therefore, to this man through the crowd that surrounded him and ascending the tribunal (for as he seemed unarmed nobody hindered him), he drew the dagger he had concealed under his garment and struck the man on the head. And the secretary being killed with one blow, Mucius was promptly seize by those who stood round the tribunal and brought before the king, who had already been informed by others of his secretary's death. Porsena, upon seeing him, said: "Most accursed of all men and destined to suffer the punishment you deserve, tell who you are and from whence you come and what assistance you counted on when you dared to commit such a deed? Did you propose to kill my secretary only, or me also? And who are your accomplices in this attempt, or privy to it? Conceal no part of the truth, les you be forced to declare it under torture."
