In the fourth month after the city was built, as Fabius writes, the adventure of stealing the women was attempted. It would seem that, observing his city to be filled by a confluence of foreigners, few of whom had wives, and that the multitude in general, consisting of a mixture of mean and obscure men, fell under contempt, and seemed to be of no long continuance together, and hoping farther, after the women were appeased, to make this injury in some measure an occasion of confederacy and mutual commerce with the Sabines, Romulus took in his hand this exploit after this manner. First, he gave it out that he had found an altar of a certain god hid under ground, perhaps the equestrian Neptune, for the altar is kept covered in the Circus Maximus at all other times, and only at horse-races is exposed to public view. Upon discovery of this altar, Romulus, by proclamation, appointed a day for a splendid sacrifice, and for public games and shows, to entertain all sorts of people; many flocked thither, and he himself sat in front, amidst his nobles, clad in purple. Now the signal for their falling on was to be whenever he rose and gathered up his robe and threw it over his body; his men stood all ready armed, with their eyes intent upon him, and when the sign was given, drawing their swords and falling on with a great shout, they stole away the daughters of the Sabines, the men themselves flying without any let or hindrance. Some say there were but thirty taken, and from Curiae or Fraternities were named; but Valerius Antias says five hundred and twenty seven, Juba, six hundred and eighty-three.
It continues a custom at this very day for the bride not of herself to pass her husband's threshold, but to be lifted over, in memory that the Sabine virgins were carried in by violence, and did not go in of their own free will. Some say, too, the custom of parting the bride's hair with the head of a spear was in token their marriages began at first by war and acts of hostility.
The Sabines were a numerous and martial people, but lived in small, unfortified villages, as it befitted, they thought, a colony of the Lacedaemonians to be bold and fearless;nevertheless, seeing themselves bound by such hostages to their good behavior, and being solicitous for their daughters, they sent ambassadors to Romulus with fair and equitable requests, that he would return their young women and recall that act of violence, and afterwards, by persuasion and lawful means, seek friendly correspondence between both nations. Romulus would not part with the young women, yet proposed to the Sabines to enter into an alliance with them; upon which point some consulted and demurred long, but Acron, king of the Ceninenses, a man of high spirit and a good warrior, who had all along a jealousy of Romulus's bold attempts, and considering particularly from this exploit upon the women that he was growing formidable to all people, and indeed insufferable, were he not chastised, first rose up in arms, and with a powerful army advanced against him. Romulus likewise prepared to receive him; but when they came within sight and viewed each other, they made a challenge to fight a single duel, the armies standing by under arms, without participation. And Romulus, making a vow to Jupiter, if he should conquer, to carry himself, and dedicate his adversary's armor to his honor, overcame him in combat, and, a battle ensuing, routed his army also, and then took his city; but did those he found in it no injury, only commanded them to demolish the place and attend him to Rome, there to be admitted to all the privileges of citizens. And indeed there was nothing did more advance the greatness of Rome, than that she did always unite and incorporate those whom she conquered into herself. Romulus, that he might perform his vow in the most acceptable manner to Jupiter, and withal make the pomp of it delightful to the eye of the city, cut down a tall oak which he saw growing in the camp, which he trimmed to the shape of a trophy, and fastened on it Acron's whole suit of armor disposed in proper form; then he himself, girding his clothes about him, and crowning his head with a laurel-garland, his hair gracefully flowing, carried the trophy resting erect upon his right shoulder, and so marched on, singing songs of triumph, and his whole army following after, the citizens all receiving him with acclamations of joy and wonder. The procession of this day was the origin and model of all after triumphs. But the statues of Romulus in triumph are, as may be seen in Rome, all on foot.
