CATO, PUBLIUS VALERIUS, Roman poet and gram marian, was born about loo B.C. He was the leader of the "new" school of poetry (poetae novi, as Cicero calls them). Its followers rejected the national epic and drama in favour of the artificial mythological epics and elegies of the Alexandrian school. The great influence of Cato is attested by the lines : Cato grammaticus, Latina Siren Qui solus legit ac facit poetas.' Our information regarding his life is derived from Suetonius (De Grammaticis, i 1). He was a native of Cisalpine Gaul, and lost his property during the Sullan disturbances before he had attained his majority. He lived to a great age and during the latter part of his life was very poor. In addition to grammatical treatises, Cato wrote a number of poems, the best known of which were the Lydia and Diana. In the Indignatio (perhaps a short poem) he defended himself against the accusation that he was of servile birth. It is probable that he is the Cato mentioned as a critic of Lucilius in the lines by an unknown author prefixed to Horace, Satires, i. 10.
Among the minor poems attributed to Virgil is one called Dirae (or rather two, Dirae and Lydia) . The Dirae consists of imprecations against the estate of which the writer has been deprived, and where he is obliged to leave his beloved Lydia ; in the Lydia, on the other hand, the estate is envied as the possessor of his charmer. Joseph Justus Scaliger was the first to attribute the poem (divided into two by F. Jacobs) to Valerius Cato, on the ground that he had lost an estate and had written a Lydia. The balance of opinion is in favour of the Dirae being assigned to the beginning of the Augustan age, although O. Ribbeck supports the claims of Cato to the authorship. The best edition of these poems is by A. F. Nake (1847), with exhaustive commentary and excursuses ; a clear account of the ques tion will be found in M. Schanz's Geschichte der romischen Literatur; for the "new" school of poetry see Mommsen, Hist. of Rome, bk. v. ch. xii. ; F. Plessis, Poesie latine (19o9) , 188.
