XXII. e. The Camenæ
BY this name the Latins designated the Muses, but included under it also some other deities, principally nymphs of fountains. Egeria was one of them, whose fountain and grotto are still shown. It was said that Numa, the second king of Rome, was favored by this nymph with secret interviews, in which she taught him those lessons of wisdom and of law which he imbodied in the institutions of his rising nation. After the death of Numa the nymph pined away and was changed into a fountain.
