There were many other sacrifices appointed by him and places dedicated for their performance which the pontiffs call the Argei. The greatest of all his works was the preservation of peace and the security of his realm throughout the whole of his reign.

Thus by two successive kings the greatness of the State was advanced; by each in a different way, by the one through war, by the other through peace. Romulus reigned thirty-seven years, Numa forty-three. The State was strong and disciplined by the lessons of war and the arts of peace.

TheTullus Hostilius and the War with Alba. death of Numa was followed by a second interregnum. Then Tullus Hostilius, a grandson of the Hostilius who had fought so brilliantly at the foot of the Citadel against the Sabines, was chosen king by the people, and their choice was confirmed by the Senate.

He was not only unlike the last king, but he was a man of more warlike spirit even than Romulus, and his ambition was kindled by his own youthful energy and by the glorious achievements of his grandfather.

Convinced that the vigour of the State was becoming enfeebled through inaction, he looked all round for a pretext for getting up a war. It so happened that Roman peasants were at that time in the habit of carrying off plunder from the Alban territory, and the Albans from Roman territory.

Gaius Cluilius was at the time ruling in Alba. Both parties sent envoys almost simultaneously to seek redress. Tullus had told his ambassadors to lose no time in carrying out their instructions; he was fully aware that the Albans would refuse satisfaction, and so a just ground would exist for proclaiming war.

The Alban envoys proceeded in a more leisurely fashion. Tullus received them with all courtesy and entertained them sumptuously. Meantime the Romans had preferred their demands, and on the Alban governor's refusal had declared that war would begin in thirty days.

When this was reported to Tullus, he granted the Albans an audience in which they were to state the object of their coming. Ignorant of all that had happened, they wasted time in explaining that it was with great reluctance that they would say anything which might displease Tullus, but they were bound by their instructions; they were come to demand redress, and if that were refused they were ordered to declare war.

“Tell your king,” replied Tullus, “that the king of Rome calls the gods to witness that whichever nation is the first to dismiss with ignominy the envoys who came to seek redress, upon that nation they will visit all the sufferings of this war.”

The Albans reported this at home. Both sides made extraordinary preparations for a war, which closely resembled a civil war between parents and children, for both were of Trojan descent, since Lavinium was an offshoot of Troy, and Alba of Lavinium, and the Romans were sprung from the stock of the kings of Alba.

The outcome of the war, however, made the conflict less deplorable, as there was no regular engagement, and though one of the two cities was destroyed, the two nations were blended into one.

The Albans were the first to move, and invaded the Roman territory with an immense army. They fixed their camp only five miles from the City and surrounded it with a moat; this was called for several centuries the “Cluilian Dyke” from the name of the Alban general, till through lapse of time the name and the thing itself disappeared. While they were encamped Cluilius, the Alban king, died, and the Albans made Mettius Fufetius dictator.

The king's death made Tullus more sanguine than ever of success. He gave out that the wrath of heaven which had fallen first of all on the head of the nation would visit the whole race of Alba with condign punishment for this unholy war. Passing the enemy's camp by a night march, he advanced upon Alban territory. This drew Mettius from his entrenchments.

He marched as close to his enemy as he could, and then sent on an officer to inform Tullus that before engaging it was necessary that they should have a conference. If he granted one, then he was satisfied that the matters he would lay before him were such as concerned Rome no less than Alba. Tullus did not reject the proposal, but in case the conference should prove illusory, he led out his men in order of battle.
