His advice to his noble friends generally inclined towards the side of prudence. Nevertheless he could not so far control his own language as to avoid the jealousy of Nero. [6] He was banished, it is not certain in what year, and apparently ended his days in exile. He left several works, mostly written in Greek; some on philosophy, of which that on the nature of the gods has come down to us in an abridged form, some on rhetoric and grammar; besides these he is said to have composed satires, tragedies, [7] and a commentary on Virgil. But his most important work was his formation of the character of one of the three Roman satirists whose works have come down to us. Few poets have been so differently treated by different critics as A. PERSIUS FLACCUS, for while some have pronounced him to be an excellent satirist and true poet, others have declared that his fame is solely owing to the trouble he gives us to read him. He was born at Volaterrae, 34 A.D., of noble parentage, brought to Rome as a child, and educated with the greatest care. His first preceptor was the grammarian Virginius Flavus, an eloquent man endued with strength of character, whose earnest moral lectures drew down the displeasure of Caligula. He next seems to have attended a course under Remmius Palaemon; but as soon as he put on the manly gown he attached himself to Cornutus, whose intimate friend he became, and of whose ideas he was the faithful exponent. The love of the pupil for his guide in philosophy is beautiful and touching; the verses in which it is expressed are the best in Persius: [8] "Secreti loquimur: tibi nunc hortante Camena Excutienda damus praecordia: quantaque nostrae Pars tua sit Cornute animae, tibi, dulcis amice, Ostendisse iuvat ... Teneros tu suscipis annos Socratico Cornute sino. Tune fallere sollers Apposita intortos extendit regula mores, Et premitur ratione animus vincique laborat, Artificemque tuo ducit sub pollice vultum." Moulded by the counsels of this good "doctor," Persius adopted philosophy with enthusiasm. In an age of licentiousness he preserved a maiden purity. Though possessing in a pre-eminent degree that gift of beauty which Juvenal declares to be fatal to innocence, Persius retained until his death a moral character without a stain. But he had a nobler example even than Cornutus by his side. He was tenderly loved by the great Thrasea, [9] whose righteous life and glorious death form perhaps the richest lesson that the whole imperial history affords. Thrasea was a Cato in justice, but more than a Cato in goodness, inasmuch as his lot was harder, and his spirit gentler and more human. Men like these clenched the theories of philosophy by that rare consistency which puts them into practice; and Persius, with all his literary faults, is the sole instance among Roman writers of a philosopher whose life was in accordance with the doctrines he professed.
