On the death of Romulus, the Senate, at first, would not allow the election of a new king. The Senators enjoyed the royal power in rotation as Inter-reges, or between-kings. In this way a year passed. But the people at length insisted that a king should be chosen, and
The Senate were obliged to give way. The choice fell upon the wise and pious Numa Pompilius, a native of the Sabine Cures who had married the daughter of Tatius. The forty-three years of Numa’s reign glided away in quiet happiness without any war or any calamity.
As Romulus was the founder of the political institutions of Rome, so Numa was the author of the religious institutions. Instructed by the nymph Egeria, whom he met in the sacred grove ofAricia, he instituted the Pontiffs, four in number, with a Pontifex Maximus at their head, who had the general superintendence of religion; the Augurs, also four in number, who consulted the will of the gods on all occasions, both private and public; three Flamens, each of whom attended to the worship of separate deities - Jupiter, Mars, and Quirinus; four Vestal Virgins, who kept alive the sacred fire of Vesta brought from Alba Longa; and twelve Salii, or priests of Mars, who had the care of the sacred shields. Numa reformed the calendar, encouraged agriculture, and marked out the boundaries of property, which he placed under the care of the god Terminus. He also built the temple of Janus, a god represented with two heads looking different ways. The gates of this temple were to be open during war and closed in time of peace.
