But it happened, unfortunately, that the rules for the interpretation of auguries and omens, were far too indefinite and vague to answer the purpose for which they were now appealed to. The most unequivocal distinctness and directness in giving its responses is a very essential requisite in any tribunal that is called upon as an umpire, to settle disputes; while the ancient auguries and oracles were always susceptible of a great variety of interpretations. When Remus and Romulus commenced their watch no vultures were to be seen from either hill. They waited till evening, still none appeared. They continued to watch through the night. In the morning a messenger came over from the Palatine hill to Remus on the Aventine, informing him that vultures had appeared to Romulus. Remus did not believe it. At last, however, the birds really came into view; a flock of six were seen by Remus, and afterward one of twelve by Romulus. The observations were then suspended, and the parties came together to confer in respect to the result; but the dispute instead of being settled, was found to be in a worse condition than ever. The point now to be determined was whether six vultures seen first, or twelve seen afterward, were the better omen, that is whether numbers, or simple priority of appearance, should decide the question. In contending in respect to this nice point the brothers became more angry with each other than ever. Their respective partisans took sides in the contest, which resulted finally in an open and violent collision. Romulus and Remus themselves seem to have commenced the affray by attacking one another. Faustulus, their foster-father, who, from having had the care of them from their earliest infancy, felt for them an almost parental affection, rushed between them to prevent them from shedding each other's blood. He was struck down and killed on the spot, by some unknown hand. A brother of Faustulus too, named Plistinus, who had lived near to him, and had known the boys from their infancy, and had often assisted in taking care of them, was killed in the endeavor to aid his brother to appease the tumult. At length the disturbance was quelled. The result of the conflict was, however, to show that Romulus and his party were the strongest. Romulus accordingly went on to build the walls of the city at the spot which he had first chosen. The lines were marked out, and the excavations were commenced with great ceremony.
