He revealed the whole story. Amulius reacted in a suspiciously friendly manner, so when he asked where the boys were Faustulus pretended that they were watching their flocks in the fields. The king sent him to find them and bring them to the palace, where they would be given a warm welcome. The old shepherd was joined by some guards, who had been given secret instructions to place Romulus and Remus under arrest. In the meantime, the king sent for Numitor, to keep an eye on him until the twins had been properly, and no doubt finally, dealt with.
However, the messenger told Numitor what was afoot and he alerted the boys, their companions, and his own retainers and friends. They forced their way into the town, which was poorly defended. Amulius was easily found and killed. His brother resumed the throne.
Skeptics who believed, as Dionysius of Halicarnassus noted, that “nothing bordering on legend or fable has any place in historical writing,” told a different tale. Numitor switched the twins with two changelings; he feared that Amulius would have them killed, and that was exactly what he did. He handed his real grandchildren to Faustulus and his wife. She was a woman of loose virtue and was nicknamed Lupa, or she-wolf, a slang term for a prostitute. The boys received a good education and were ready for public life when the coup against Amulius succeeded.
ONE WAY OR another, this brought to a satisfactory conclusion the story of one brace of brothers but left the future of the other pair in some doubt. What was to be done with these headstrong youths? They were eager for political power, but with the restoration of their grandfather that was not on offer at Alba Longa. However, the population in the kingdom was growing and there were enough adventurers to found a new city. Here was a suitable task for Romulus and Remus (and one that, one may guess, prompted Numitor to heave a sigh of relief).
The brothers decided that the group of hills on the Tiber would be an ideal place for a new city. The ford would allow those who controlled it to manage traffic going up and down the western plain; the hills would assure easy defense from attack; and the Tiber, navigable up to this point, would enable trade and access to salt flats where it met the sea; later, a road to the river mouth was to be called the via Salaria, the Salt Road.
Cicero, looking back from the first century B.C., was in no doubt that the choice of site was crucial to Rome’s later success:
A river enables the city to use the sea both for importing what it lacks and for exporting what it produces as a surplus; and by its means too the city can not only bring in by sea but also obtain from the land, carried on its waters, whatever is most essential for its life and civilization. Consequently it seems to me that Romulus must at the very beginning have had a divine intimation that the city would one day be the seat and hearthstone of a mighty empire.
The brothers decided that, as a start, they would fortify one of the hills, but they could not agree on which one. Romulus opted for the Palatine, and Remus the neighboring Aventine. Neither would give way, so they went back to Alba and asked their grandfather’s advice on how to resolve the quarrel. He proposed that each stand on his chosen hill and, after making a sacrifice to the gods, watch for the flight of birds, a traditional method of discovering the divine will. The decision would go to the one who saw the most auspicious kind of bird.
Remus struck lucky first, for six vultures flew past his vantage point. Romulus, not to be outdone, falsely claimed to have seen twelve vultures. Remus didn’t believe him. But when he walked over to the Palatine and challenged his brother, he saw that twelve vultures had in fact just put in an appearance. The question remained undecided, for both men had seen the same kind of bird. Remus claimed victory because he had been the first to spot vultures, and Romulus insisted that he had won because he had seen the largest number of vultures.
Remus lost his temper and made some unkind remarks about a defensive trench Romulus had begun to dig on the Palatine. He jumped scornfully across it, and his brother, now furious as well, attacked him. Their friends and followers joined in the fight. Faustulus, who was present, threw himself unarmed into the melée in an attempt to separate the combatants. He was struck down and killed for his pains. Remus, too, lost his life, at his brother’s hands. In Varro and Cicero’s day, an old stone lion in the Forum was believed to mark Faustulus’s grave.
As calm returned, Romulus realized what he had done. He had founded his new state on a crime. And not just any crime, for he had broken one of the most sacred taboos by committing fratricide. The rivalry of brothers was a common theme in the ancient world—the sons of Oedipus, Eteocles and Polynices, killed one another in a duel—and in the Bible story Cain murdered Abel. But it was something new when the foundation myth of a state originated in brotherly hatred and violence. For Romans in the dying years of the Republic, this was a fearful anticipation of the fratricidal civil wars that led to the decimation of Rome’s ruling class.
FILLED WITH GRIEF and remorse, Romulus lost all desire for life—at least for a while. Ambition returned, and he finally built his city on the hill. This was a religious as well as a political act. A foundation pit, the mundus, a symbolic entrance to the underworld, was dug, in which clods of earth and first fruits were deposited. Then Romulus, as leader or king, yoked a plow to a bull and a cow and drove a deep furrow around the boundary lines. This marked the pomerium, or city limits; it was sacred, and only from inside it could priests watch for the movement of birds and so determine the pleasure of the gods. The city walls, or fortifications, were laid out behind this line and the space on either side was kept free of buildings, graves, and plants. (This ceremony was repeated whenever Rome, in later times, founded a colonia, or colony town.)
Romans of the late Republic were eager to determine the date of the foundation of Rome. There was widespread agreement that it took place in the eight century B.C., but there was fierce argument about the exact year. Computations included 728 and 751 B.C., but the date that won the most support came from Cicero’s greatest friend, a learned multimillionaire named Atticus, and Varro, who proposed 753 B.C. Even today, this year appears in modern histories as Rome’s traditional birthday. Varro was the kind of antiquarian who was fascinated by obscure calculation; he once invited an astrologer to work out from the study of Romulus’s life the date of his birth. In what was in effect a reverse horoscope, the man concluded:
[Romulus] was conceived in his mother’s womb in the first year of the second Olympiad, in the month Choeac of the Egyptian calendar, on the twenty-third day, and in the third hour, when the sun was totally eclipsed; and … he was born in the month Thoth, on the twenty-first day, at sunrise.
Or, in other words, 772 B.C.
This first Rome housed a preliminary population of little more than three thousand Latins. If Romulus was to build a viable community, able not only to man its defenses but also to supply labor for the variety of trades that people would expect of it, he needed more citizens. He established a policy of offering foreigners the gift of Roman nationality, a welcoming approach that lasted a thousand years.
His first measure was to open a sanctuary where exiles, the dispossessed, and criminals and escapees of every kind, freemen or slaves, could take refuge. A miscellaneous rabble soon collected. (The story bears some resemblance to the beginnings of Australia.) It now emerged that there were too few women to go around the growing number of male citizens. Something urgent and decisive had to be done to achieve a one-to-one gender balance.
