There was a grove, the middle of which was irrigated by a spring of running water, issuing from a dark grotto. As Numa went often thither alone, under pretence of conferring with the goddess, he dedicated the place to the Muses, because their meetings with his wife Egeria were held there. He also instituted a yearly festival to Faith alone, and commanded the priests to be carried to her temple in an arched chariot drawn by two horses, and to perform the divine service with their hands wrapt up to the fingers, intimating that Faith ought to be protected, and that her seat ought to be sacred even in men's right hands. He instituted many other sacred rites, and dedicated places for performing them, which the priests call Argei. But the greatest of all his works was his maintenance of peace, during the whole period of his reign, no less than of his royal prerogative. Thus two kings in succession, by different methods, the one by war, the other by peace, aggrandized the state. Romulus reigned thirty-seven years, Numa forty-three: the state was both strong and well versed in the arts of war and peace.

Romulus, 1st King of Rome (and his brother Remus)
The vestal Rhea, being deflowered by force, when she had brought forth twins, declares Mars to be the father of her illegitimate offspring, either because she believed it to be so, or because a god was a more creditable author of her offence. But neither gods nor men protect her or her children from the king's cruelty: the priestess is bound and thrown into prison; the children he commands to be thrown into the current of the river. By some interposition of providence, the Tiber having overflowed its banks in stagnant pools, did not admit of any access to the regular bed of the river; and the bearers supposed that the infants could be drowned in water however still; thus, as if they had effectually executed the king's orders, they expose the boys in the nearest land-flood, where now stands the ficus Ruminalis (they say that it was called Romularis)...The tradition is, that when the water, subsiding, had left the floating trough, in which the children had been exposed, on dry ground, a thirsty she-wolf, coming from the neighbouring mountains, directed her course to the cries of the infants, and that she held down her dugs to them with so much gentleness, that the keeper of the king's flock found her licking the boys with her tongue.
