147 C. VALERIUS TRIARIUS
C. Valerius Triarius (RE Valerius 365), a brother of P. Valerius Triarius (148), supported Cn. Pompeius Magnus (111) in the civil war and may have fallen in the battle of Pharsalus (Caes. BCiv. 3.5, 3.92).
T 1 Cic. Fin. 1.13–14
[Cicero:] accurate autem quondam a L. Torquato, homine omni doctrina erudito, defensa est Epicuri sententia de voluptate, a meque ei responsum, cum C. Triarius, in primis gravis et doctus adulescens, ei disputationi interesset.  nam cum ad me in Cumanum salutandi causa uterque venisset, pauca primo inter nos de litteris, quarum summum erat in utroque studium, deinde Torquatus, “quoniam nacti te,” inquit, “sumus aliquando otiosum, certe audiam quid sit quod Epicurum nostrum non tu quidem oderis, ut fere faciunt qui ab eo dissentiunt, sed certe non probes, eum quem ego arbitror unum vidisse verum maximisque erroribus animos hominum liberavisse et omnia tradidisse quae pertinerent ad bene beateque vivendum. sed existimo te, sicut nostrum Triarium, minus ab eo delectari quod ista Platonis, Aristoteli, Theophrasti
when others did.” ...  “But the same men did not support those who were on trial for the conspiracy before him [Sulla].”
147 C. VALERIUS TRIARIUS
C. Triarius is present at the dialogues recorded in Cicero’s De finibus 1 and 2 (e.g., T 1).
In Cicero the mature, learned, and earnest oratory of C. Triarius is mentioned favorably (T 2).
T 1 Cicero, On Ends
[Cicero:] And Epicurus’ views on pleasure were once defended meticulously by L. Torquatus [L. Manlius Torquatus (146)], a man well versed in all kinds of learning; a reply to him was given by me, while C. Triarius, a particularly serious and learned young man, took part in that discussion.  When both of them had come to pay me their respects at my place at Cumae, there were first a few remarks among us about literature, of which both were enthusiastic students. Then Torquatus said: “As we have for once found you at leisure, I am resolved to hear the reason why it is that you regard our Epicurus, not indeed with hatred, as those who disagree with him mostly do, but certainly with disapproval: I myself consider him as the one person who has discerned the truth and who has delivered the minds of men from the gravest errors and imparted to them everything that concerns living well and happily. But I believe that you, like our friend Triarius, are less pleased by him because he has neglected those ornaments of speech found in Plato, Aristotle, and Theophrastus.
