Brutus, who had gained his eminence by swearing that there should be no monarch or single ruler in Rome, found himself in sole possession of the supreme authority. His position presents nothing very remarkable to the modern observer, who is accustomed to see those who have denounced a system yesterday participating in the profits of the same system to-day, and declaring their own arguments to be thoroughly out of place, as applied to themselves when in office. Brutus, however, could not consistently exercise a power he had sworn to overthrow; and to carry out his anti-monarchical principles, he had either to go out himself, or to ask for a colleague. On the same principle that prefers the half quartern to utter loaflessness, Brutus proposed a partnership in the government; and Collatinus was taken into the firm, which proved to have no firmness at all, for it was dissolved very speedily. The difficulty of agreement between two of the same trade was severely felt by the two popular reformers, who were dividing the substance without the name of that power they had vowed to destroy; it was soon evident that if they had thought it too much for one, they considered it not enough for two; and they were accordingly always quarrelling. To prevent collision, they tried the experiment of taking the supreme authority by turns, each assuming the fasces for a month at a time; but this alternate chopping of the regal sticks, or fasces, which were the emblems of power, led to nothing satisfactory. A question at length arose, upon which the duality of the ruling mind was so distinctly marked, that the two consuls, whose very name is derived from _con_, with, and _salio_, to leap, were trying to leap in two opposite ways; and an end of their own power was the only conclusion to which they were likely to jump together. Tarquin had retired to Caere, waiting the chances of a restoration of his line; but his line had fallen into such contempt, that he was fishing in vain for his recall, though he nevertheless sent ambassadors to demand the restoration of himself, or at all events of his private property. The senate decreed that though Tarquin could not have the fasces, he was at liberty to make a bundle of all the other sticks that might belong to him. On this question Brutus and Collatinus were violently opposed, and both becoming hot, their excessive warmth led to a mutual coolness that ended in an open hostility, which shut out every hope of compromise. Collatinus gave in by going out, and was succeeded by P. Valerius, one of the party of four who had roused the popular spirit over the bier of Lucretia.
