M. Porcius Cato, the Censor (B.C. 234-149), born at Tusculum, of a yeoman stock, was one of the most prominent figures of his time. For the best account of his military and political career, including his advancement to the Consulship (B.C. 195) and Censorship (B.C. 184), and his economic and social reforms, the reader may be referred to Mommsen, _R.H._, vol. ii. _passim_. Cato was the founder of Latin prose, and the chief opponent of the exaggerated Hellenism that was finding its way into Roman life and literature (cf. his own words quoted by Pliny, _N.H._ xxix. 14, 'Quandoque ista gens suas litteras dabit, omnia corrumpet'); but even he shows traces of Greek influence. Cato is represented now only by (1) his treatise _De Agri Cultura_, the earliest extant work in Latin prose, which, besides giving instruction for the husbandman, deals with housekeeping, cookery, and medicine. (2) His great work was the _Origines_, the earliest history in Latin prose, the contents of which are enumerated by Nepos, _Cato_, 3, 3, 'Senex historias scribere instituit. Earum sunt libri vii. Primus continet res gestas regum populi Romani, secundus et tertius unde quaeque civitas orta sit Italica (ob quam rem omnes Origines videtur appellasse); in quarto autem bellum Poenicum est primum, in quinto secundum. Atque haec omnia capitulatim sunt dicta. Reliqua quoque bella pari modo persecutus est usque ad praeturam Ser. Galbae, qui diripuit Lusitanos (B.C. 151). Atque horum bellorum duces non nominavit, sed sine nominibus res notavit.[22] In eisdem exposuit quae in Italia Hispaniisque aut fierent aut viderentur admiranda: in quibus multa industria et diligentia comparet, nulla doctrina.' An attempt has been made by A. Bormann (_M. Porcii Catonis Originum Libri vii._, Brandenburg 1858, p. 38) to prove that the principle of division was geographical, and that history only came in incidentally in connexion with the reduction of provinces; but as Nepos was writing to an eminent authority on antiquities, his account is likely to be right. The period between the kings and the Punic Wars was probably omitted by Cato through want of authorities. The title _Origines_ fails to indicate the scope of the work, which was chiefly occupied with general history; it was probably taken, as Nepos suggests, from the contents of Books ii. and iii., which seem to have been the most novel and valuable part of the undertaking. (Jordan, however, takes 'Origines' as equivalent, not to the Greek κτίσεις, but to 'res Romanae ab origine repetitae.') (3) _Praecepta ad Filium_ was the general title of a didactic work containing rules for medicine, husbandry, and rhetoric (_e.g._ 'Rem tene, verba sequentur'). Cf. Quint. iii. 1, 19, 'Romanorum primus, quantum ego quidem sciam, condidit aliqua in hanc materiam (rhetoric) M. Cato ille Censorius.'
