The progress of Roman culture is distinctly shown by a comparison of the curriculum of Cato with that of Marcus Terentius Varro, a long-time friend of Cicero, though ten years his senior. [Footnote: Varro is said to have written of his youth. "For me when a boy there sufficed a single rough coat and a single undergarment, shoes without stockings, a horse without a saddle. I had no daily warm bath, and but seldom a river bath." Still, he utters warnings against over-feeding and over- sleeping, as well as against cakes and high living, pointing to his own youthful training, and says that dogs were in his later years more judiciously cared for than children.] Varro obtained from Quintilian the title "the most learned of the Romans," and St. Augustine said that it was astonishing that he could write so much, and that one could scarcely believe that anybody could find time even to read all that he wrote. He was proscribed by the triumvirs at the same time that Cicero was, but was fortunate enough to escape and subsequently to be placed under the protection of Augustus. Cato thought that a proper man ought to study oratory, medicine, husbandry, war, and law, and was at liberty to look into Greek literature a little, that he might cull from the mass of chaff and rubbish, as he affected to deem it, some serviceable maxims of practical experience, but he might not study it thoroughly. Varro extended the limit of allowed and fitting studies to grammar, logic, rhetoric, geometry, arithmetic, astronomy, music, medicine, and architecture.
