Plutarch, Marcus Cato
Bernadotte Perrin, Ed.

17. As censor, then, Cato made Lucius Valerius Flaccus, his colleague and friend, chief senator. He also expelled many members of the Senate, including Lucius Quintius. This man had been consul seven years before, and, a thing which gave him more reputation than the consulship even, was brother of the Titus Flamininus who conquered King Philip.¹ [2] The reason for his expulsion was the following. There was a youth who, ever since his boyhood, had been the favourite of Lucius. This youth Lucius kept ever about him, and took with him on his campaigns in greater honour and power than any one of his nearest friends and kinsmen had. He was once administering the affairs of his consular province, and at a certain banquet this youth, as was his wont, reclined at his side, and began to pay his flatteries to a man who, in his cups, was too easily led about. ‘I love you so much,’ he said, ‘that once, when there was a gladiatorial show at home, a thing which I had never seen, I rushed away from it to join you, although my heart was set on seeing a man slaughtered.’ [3] ‘Well, for that matter,’ said Lucius, ‘don't lie there with any grudge against me, for I will cure it.’ Thereupon he commanded that one of the men who were lying under sentence of death be brought to the banquet, and that a lictor with an axe stand by his side. Then he asked his beloved if he wished to see the man smitten. The youth said he did, and Lucius ordered the man's head to be cut off.

[4] This is the version which most writers give of the affair, and so Cicero has represented Cato himself as telling the story in his dialogue ‘On Old Age.’ ² But Livy³ says the victim was a Gallic deserter, and that Lucius did not have the man slain by a lictor, but smote him with his own hand, and that this is the version of the story in a speech of Cato's.

[5] On the expulsion of Lucius from the Senate by Cato, his brother was greatly indignant, and appealed to the people, urging that Cato state his reasons for the expulsion. Cato did so, narrating the incident of the banquet. Lucius attempted to make denial, but when Cato challenged him to a formal trial of the case with a wager of money upon it, he declined. Then the justice of his punishment was recognized. [6] But once when a spectacle was given in the theatre, he passed along by the senatorial seats, and took his place as far away from them as he could. Then the people took pity upon him and shouted till they had forced him to change his seat, thus rectifying, as far as was possible, and alleviating the situation.

[7] Cato expelled another senator who was thought to have good prospects for the consulship, namely, Manilius, because he embraced his wife in open day before the eyes of his daughter. For his own part, he said, he never embraced his wife unless it thundered loudly; and it was a pleasantry of his to remark that he was a happy man when it thundered.
