It is by no means certain that the consulship was instituted immediately after the expulsion of the kings. Rome was perhaps at first under the rule of the four Tribunes of the Celeres; perhaps also the government was at once rid of its superfluous number of heads, and they were reduced to two. This was certainly a deterioration; yet it may have been so ordered in Servius’ constitution with the definite purpose of securing the equalization of the commonalty, so that there might be one consul from the patricians, and one from the plebeians. In this case, of the first consuls Collatinus is the patrician and Brutus the plebeian one, unless perhaps there should yet happen to be a prior consulate of Sp. Lucretius and Valerius Poplicola. The taking of Rome by the Gauls has not been fraught with more serious consequences to the city itself than it has been to its history, of which indeed all the sources have been obliterated by it. The chronicles of many places in their early histories afford a parallel to this. In Dittmarsch they begin about a hundred and fifty years before the conquest of the country, after the great change when the clans and the peasantry were formed into one organized body; an event which they do not mention, but presuppose. In like manner the chronicle of Cologne commences its notices long after that city was already great and flourishing. There were every where in the middle ages earlier written accounts; yet they were laid on the shelf, as they had no more any positive interest, after the particulars of the tradition had been buried in oblivion. Thus it was also with Roman history. They had it from the times of the republic, not, however, from its beginning, but only from about the period of the Secessio, merely with detached notices of the earlier times; before it they had nothing besides the peace with the Sabines during Sp. Cassius’ first consulate, and the war with the Volscians. All those earlier histories were, as we have already shown, restored in accordance with a numerical scheme.
