The work of Cato, “De Re Rustica,” has come down to us almost in form and substance as it was written. It has not the method of a regular treatise. It is a commonplace-book of agriculture and domestic economy under one hundred and sixty-three heads. The subjects are connected, but not regularly arranged; they form a collection of useful instructions, hints, and receipts. Its object is utility, not science. It serves the purposes of a farmers’ and gardeners’ manual; a domestic medicine, an herbal, and cookery-book; prudential maxims are interspersed, and some favourite charms for the cure of diseases in man and beast. Cato teaches his readers, for example, how to plant ozier-beds, to cultivate vegetables, to preserve the health of cattle, to pickle pork, and to make savoury dishes. He is shrewd and economical, but he never allows humanity to interfere with profits; for he recommends his readers to sell every thing which they do not want, even old horses and old slaves. He is a great conjurer, for he informs us that the most potent cure for a sprain is the repetition of the following hocus-pocus:[337] “Daries dardaries, astataries dissunapitea;” or, “Huat hanat, huat hista, pista sista, domiabo damnaustra;” or, “Huat huat, huat, ista sis tar sis, ordannabon damnaustra.” This miscellaneous collection is preceded by an introduction, in which is maintained the superiority of agriculture over other modes of gaining a livelihood, especially over that of trade and money-lending. Cato was a conscientious father. He could not trust Greeks, but undertook the education of his son himself. As a part of his system, he addressed to him, in the form of letters, instruction on various topics—historical, philosophical, and moral. A very few fragments of this work, unfortunately, remain. In one of them he recommends a cursory view of Greek literature, but not a profound study of it. He evidently considered Greek writings morally dangerous; but he entertained a still greater horror of their medicine. He had confidence in his own old-fashioned charms and rural pharmacopeia; but he firmly believed, as he would the voice of an oracle, that all the Greek physicians were banded together to destroy the Romans as barbarians.
