Scipio opens the second book with the origin of the Roman people, adopting the received opinions concerning the early history of Rome, of Romulus, and the succeeding kings. These opinions have of late, been much controverted. Niebuhr whose erudition appears to be inimitable, whatever success he may be thought to have had in shaking them, has substituted nothing satisfactory in their place, at least as far as we may gather from his first volume. One thing may be safely asserted, that Cicero might well present in his republic, those traditions of the times, as the real history of his country, because the Roman people were acquainted with no other. He could not call upon them to venerate the founders of Rome and their institutions, and tell them at the same time they had never existed. Niebuhr himself strengthens the account given at section 19, Book II., of the Greek descent of the first Tarquin, by observing that the clay vases made at Tarquinii were painted, and resembled in colour and drawing some discovered near Corinth. He says they are found only in the district of Tarquinii, and that the circumstance implies a peculiar intercourse between Corinth and Tarquinii. In the 22d section of the 2d Book, is another passage with which Niebuhr is not satisfied, and which even Professor Mai terms “vexatissimum locum.” Cicero says the Roman people were distributed by Servius into six classes, whose entire elective force was one hundred and ninety-three centuries. To give the landed proprietors who were rated in the first class, a majority of this number, or ninety-seven votes, three centuries of horse with six suffrages, meaning those inscribed in the great census or register, in contradistinction to the horsemen set apart from the mass of the whole people; the century of carpenters, and the first class, constituted together eighty-nine centuries. Eight more centuries taken from the other five classes and added to this number, made ninety-seven, being a majority of one over ninety-six, and thus in Cicero’s words “Confecta est vis, populi universa.” The unwearied erudition of Niebuhr, to which great deference is due, is not satisfied with the simplicity of this statement of the Roman Constitution, but assails it with an unusual bitterness of critical spirit. He supposes the passage from its genuine state to have been corrupted by successive transcribers and commentators, to the order in which Professor Mai has thought proper to give it to the public, and that in its original state it stood thus. “Nunc rationem videtis esse talem ut prima classis, addita centuria quæ ad summum usum urbis fabris tignariis est data: LXXXI centurias habeat; quibus ex CXIV centuriis, tot enim reliquæ sunt, equitum centuriæ cum sex suffragiis solæ si accesserunt,” &c.
