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. This trophy was styled an offering to Jupiter Feretrius, from ferire, which in Latin is to smite; for Romulus prayed he might smite and overthrow his enemy; and the spoils were called opima, or royal spoils, says Varro, from their richness, which the word opes signifies; though one would more probably conjecture from opus, an act; for it is only to the general of an army who with his own hand kills his enemies' general
