The attention of the whole people having been thus diverted from violence and arms to the deliberation and adjustment of these matters, both their minds were engaged in some occupation, and the watchfulness of the gods now constantly impressed upon them, as the deity of heaven seemed to interest itself in human concerns, had filled the breasts of all with such piety, that faith and religious obligations governed the state, the dread of laws and punishments being regarded as secondary. And while the people of their own accord were forming themselves on the model of the king, as the most excellent example, the neighbouring states also, who had formerly thought that it was a camp, not a city, that had been established in their midst to disturb the general peace, were brought to feel such respect for them that they considered it impious to molest a state, wholly occupied in the worship of the gods. There was a grove, the middle of which was irrigated by a spring of running water, flowing from a dark grotto. As Numa often repaired thither unattended, under pretence of meeting the goddess, he dedicated the grove to the Camenae, because, as he asserted, their meetings with his wife Egeria were held there. He also instituted a yearly festival to Faith alone, and commanded her priests to be driven to the chapel erected for the purpose in an arched chariot drawn by two horses, and to perform the divine service with their hands wrapped up to the fingers, intimating that Faith ought to be protected, and that even her seat in men's right hands was sacred. He instituted many other sacred rites, and dedicated places for performing them, which the priests call Argei. But the greatest of all his works was the maintenance of peace during the whole period of his reign, no less than of his royal power. Thus two kings in succession, by different methods, the one by war, the other by peace, aggrandized the state. Romulus reigned thirty-seven years, Numa forty-three: the state was both strong and attempered by the arts both of war and peace.
Upon the death of Numa, the administration returned again to an interregnum. After that the people appointed as King Tullus Hostilius, the grandson of that Hostilius who had made the noble stand against the Sabines at the foot of the citadel: the fathers confirmed the choice. He was not only unlike the preceding king, but even of a more warlike disposition than Romulus. Both his youth and strength, and, further, the renown of his grandfather, stimulated his ambition. Thinking therefore that the state was deteriorating through ease, he everywhere sought for an opportunity of stirring up war. It so happened that some Roman and Alban peasants mutually plundered each other's lands. Gaius Cluilius at that time was in power at Alba. From both sides ambassadors were sent almost at the same time, to demand satisfaction. Tullus had ordered his representatives to attend to their instructions before anything else. He knew well that the Alban would refuse, and so war might be proclaimed with a clear conscience. Their commission was executed in a more dilatory manner by the Albans: being courteously and kindly entertained by Tullus, they gladly took advantage of the king's hospitality. Meanwhile the Romans had both been first in demanding satisfaction, and upon the refusal of the Alban, had proclaimed war upon the expiration of thirty days: of this they gave Tullus notice. Thereupon he granted the Alban ambassadors an opportunity of stating with what demands they came. They, ignorant of everything, at first wasted some time in making excuses: That it was with reluctance they would say anything which might be displeasing to Tullus, but they were compelled by orders: that they had come to demand satisfaction: if this was not granted, they were commanded to declare war. To this Tullus made answer, "Go tell your king, that the king of the Romans takes the gods to witness, that, whichever of the two nations shall have first dismissed with contempt the ambassadors demanding satisfaction, from it they [the gods] may exact atonement for the disasters of this war." This message the Albans carried home.
Preparations were made on both sides with the utmost vigour for a war very like a civil one, in a manner between parents and children, both being of Trojan stock: for from Troy came Lavinium, from Lavinium, Alba, and the Romans were descended from the stock of the Alban kings. However, the result of the war rendered the quarrel less distressing, for the struggle never came to regular action, and when the buildings only of one of the cities had been demolished, the two states were incorporated into one. The Albans first invaded the Roman territories with a large army. They pitched their camp not more than five miles from the city, and surrounded it with a trench, which, for several ages, was called the Cluilian trench, from the name of the general, till, by lapse of time, the name, as well as the event itself, was forgotten. In that camp Cluilius, the Alban king, died: the Albans created Mettius Fufetius dictator. In the meantime Tullus, exultant, especially at the death of the king, and giving out that the supreme power of the gods, having begun at the head, would take vengeance on the whole Alban nation for this impious war, having passed the enemy's camp in the night-time, marched with a hostile army into the Alban territory. This circumstance drew out Mettius from his camp: he led his forces as close as possible to the enemy; thence he despatched a herald and commanded him to tell Tullus that a conference was expedient before they came to an engagement; and that, if he would give him a meeting, he was certain he would bring forward matters which concerned the interests of Rome no less than of Alba. Tullus did not reject the offer: nevertheless, in case the proposals made should prove fruitless, he led out his men in order of battle: the Albans on their side marched out also. After both armies stood drawn up in battle array, the chiefs, with a few of the principal officers, advanced into the midst. Then the Alban began as follows: "That injuries and the non-restitution of property claimed according to treaty is the cause of this war, methinks I have both heard our king Cluilius assert, and I doubt not, Tullus, but that you allege the same. But if the truth must be told, rather than what is plausible, it is thirst for rule that provokes two kindred and neighbouring states to arms. Whether rightly or wrongly, I do not take upon myself to determine: let the consideration of that rest with him who has begun the war. As for myself, the Albans have only made me their leader for carrying on that war. Of this, Tullus, I would have you advised: how powerful the Etruscan state is around us, and around you particularly, you know better than we, inasmuch as you are nearer to them. They are very powerful by land, far more so by sea. Recollect that, directly you shall give the signal for battle, these two armies will be the object of their attention, that they may fall on us when wearied and exhausted, victor and vanquished together. Therefore, for the love of heaven, since, not content with a sure independence, we are running the doubtful hazard of sovereignty and slavery, let us adopt some method, whereby, without great loss, without much bloodshed of either nation, it may be decided which is to rule the other." The proposal was not displeasing to Tullus, though both from his natural bent, as also from the hope of victory, he was rather inclined to violence. After consideration, on both sides, a plan was adopted, for which Fortune herself afforded the means of execution.
It happened that there were in the two armies at that time three brothers born at one birth, neither in age nor strength ill-matched. That they were called Horatii and Curiatii is certain enough, and there is hardly any fact of antiquity more generally known; yet in a manner so well ascertained, a doubt remains concerning their names,
