The Roman History: Concerning the Kings (5-7)

When Tatius waged war against Romulus, the wives of the Romans, who were daughters of the Sabines, made peace between them. Advancing to the camp of the parents they held out their hands to them and showed the infant children already born to them and their husbands, and testified that their husbands had done them no wrong. They prayed that the Sabines would take pity on themselves, their sons-in-law, their grandchildren, and their daughters, and either put an end to this wretched war between relatives, or first kill them in whose behalf it was begun. The parents, moved partly by their own difficulties and partly by pity for the women, and perceiving that what the Romans had done was not from lust but necessity, entered into negotiations with them. For this purpose Romulus and Tatius met in the street which was named from this event Via Sacra and agreed upon these conditions: that both Romulus and Tatius should be kings, and that the Sabines who were then serving in the army under Tatius, and any others who might choose to come, should be allowed to settle in Rome on the same terms and under the same laws as the Romans themselves.

The general, learning this fact from one of his personal friends, communicated it to Hostilius.

Some blamed him [Tullus Hostilius] because he wrongly staked everything on the prowess of three men (the Horatii).
