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.
