the war eventually ended in a Roman victory. The enemy population was brought to Rome and, as usual with defeated foes, given Roman citizenship. But its city was destroyed. Livy wrote: “Every building, public and private, was leveled with the ground. In a single hour the work of four hundred years lay in utter ruin.” It was as if Alba Longa had never existed. This would not be the last time that Rome annihilated an enemy city, giving full rein to the hatred caused by fear.
THERE WERE TWO ways of crossing the Tiber. One could walk or drive a vehicle across a ford that led to a river island, the Insula Tiberina, and then another ford by which one reached the far bank. This was not very convenient, though, and the alternative was a ferry much used by traders in salt on their way to and from the salt flats at the river mouth.
One of the achievements of Ancus Marcius, Tullus’s successor, was to replace the ferry with Rome’s first bridge, thePons Sublicius. It was made of wood and, for some forgotten ritual scruple, the use of metal in its construction was strictly forbidden. Its repair was the responsibility of Rome’s leading college of priests, the pontifices (the name means “bridge builders”). It was frequently destroyed by floods, and its rebuilding was a religious duty. The bridge survived for about a thousand years and was probably not removed until the fifth century A.D .
Religion also entered into the process of declaring war. The Romans believed that they would arouse divine anger if they went to war on a false prospectus. The cause had to be just. Ancus Marcius was credited with devising a ritual formula that kept Rome on the right side of the law.
When some offense, some casus belli, had been committed, the head of a delegation, or the pater patratus (“father in charge”), accompanied by three other colleagues (drawn from a college of priests called fetiales ) traveled to the border of the state from whom satisfaction was sought. He covered his head in a woolen bonnet and announced, “Hear me, Jupiter! Hear me, land of So-and-So! I am the accredited spokesman of the Roman People. I come as their envoy in the name of justice and religion, and ask credence for my words.” He then spelled out the particulars of the alleged offense and, calling Jupiter as witness, concluded, “If my demand for the restitution of these men, or those goods, be contrary to religion and justice, then never let me be a citizen of my country.”
The embassy then crossed the frontier and the pater patratus repeated the formula to the first (presumably somewhat startled) person he met, and again at the state’s city gates, and one final time in the marketplace. If his demands were not conceded within thirty days, he proceeded to a formal declaration of war, calling on not only the leader of the gods but on the god of gates and doorways, of beginnings and endings: “Hear, Jupiter; hear, Janus Quirinus; hear, all you gods in heaven, on the earth and under the earth: I call you to witness that the people of So-and-So are unjust and refuse reparation. But concerning these things we will consult the elders of our country, how we may obtain our due.”
If their complaint was not accepted, the envoys returned home and discussed the position with the Senate. Each member was asked his view and, typically, replied, “I hold that these things be sought by means of just and righteous war. Thus I give my vote and my consent.” If a majority agreed, then one of the fetiales returned tothe enemy frontier and formally declared war. He flung a spear across the frontier as a sign that hostilities had begun.
In later years, with the enlargement of Rome’s territory this procedure became increasingly difficult to apply. A piece of land was therefore acquired in the city which was symbolically designated as hostile soil and into which the spear could be thrown. A specially appointed senator replaced the fetiales . But the principle of
