This method which Numa used made it believed that he had been much conversant with Pythagoras; for in the philosophy of the one, as in the policy of the other, man's relations to the deity occupy a great place. It is said, also, that the solemnity of his exterior garb and gestures was adopted by him from the same feeling with Pythagoras. For it is said of Pythagoras, that he had taught an eagle to come at his call, and stoop down to him in his flight; and that, as he passed among the people assembled at the Olympic games, he showed them his golden thigh; besides many other strange and miraculous seeming practices, on which Timon the Philasian wrote the distich-"Who, of the glory of a juggler proud, With solemn talk imposed upon the crowd."In like manner Numa spoke of a certain goddess or mountain nymph that was in love with him, and met him in secret, as before related;and professed that he entertained familiar conversation with the Muses, to whose teaching he ascribed the greatest part of his revelations; and amongst them, above all, he recommended to the veneration of the Romans one in particular, whom he named Tacita, the silent; which he did perhaps in imitation and honour of the Pythagorean silence. His opinion, also, of images is very agreeable to the doctrine of Pythagoras; who conceived of the first principle of being as transcending sense and passion, invisible and incorrupt, and only to be apprehended by abstract intelligence. So Numa forbade the Romans to represent God in the form of man or beast, nor was there any painted or graven image of a deity admitted amongst them for the space of the first hundred and seventy years, all of which time their temples and chapels were kept free and pure from images; to such baser objects they deemed it impious to liken the highest, and all access to God impossible, except by the pure act of the intellect. His sacrifices, also, had great similitude to the ceremonial of Pythagoras, for they were not celebrated with effusion of blood, but consisted of flour, wine, and the least costly offerings. Other external proofs, too, are urged to show the connection Numa had with Pythagoras. The comic writer Epicharmus, an ancient author, and of the school of Pythagoras, in a book of his dedicated to Antenor, records that Pythagoras was made a freeman of Rome. Again, Numa gave to one of his four sons the name of Mamercus, which was the name of one of the sons of Pythagoras; from whence, as they say, sprang that ancient patrician family of the Aemilli, for that the king gave him in sport the surname of Aemilius, for his engaging and graceful manner in speaking. I remember, too, that when I was at Rome, I heard many say, that, when the oracle directed two statues to be raised, one to the wisest and another to the most valiant man in Greece, they erected two of brass, one representing Alcibiades, and the other Pythagoras.
But to pass by these matters, which are full of uncertainty and not so important as to be worth our time to insist on them, the original constitution of the priests, called Pontifices, is ascribed unto Numa, and he himself was, it is said, the first of them; and that they have the name of Pontifices from potens, powerful, because they attend the service of the gods, who have power to command over all.
Others make the word refer to exceptions of impossible cases; the priests were to perform all the duties possible to them; if anything lay beyond their power, the exception was not to be cavilled at. The most common opinion is the most absurd, which derives this word from pons, and assigns the priests the title of bridge-makers. The sacrifices performed on the bridge were amongst the most sacred and ancient, and the keeping and repairing of the bridge attached, like any other public sacred office, to the priesthood. It was accounted not simply unlawful, but a positive sacrilege, to pull down the wooden bridge; which moreover is said, in obedience to an oracle, to have been built entirely of timber and fastened with wooden pins, without nails or cramps of iron. The stone bridge was built a very long time after when Aemilius was quaestor, and they do, indeed, say also that the wooden bridge was not so old as Numa's time, but was finished by Ancus Marcius, when he was king, who was the grandson of Numa by his daughter.
