Instances are recorded in history, from time to time, where the philosophers attempted to explain to the people the natural meaning of those things which they believed were pregnant with supernatural import. On a certain occasion, a ram with one horn was found on the farm of Pericles, and, from this circumstance, an Athenian diviner, named Lampon, predicted that the party of the orator would triumph over the opposite faction and gain control of the government. Whereupon Anaxagoras dissected the skull, and demonstrated to the people the natural cause of the phenomenon in the peculiar shape of the animal's brain. But this reformer finally suffered the fate of other innovators, was prosecuted for impiety, and was only saved by the influence of Pericles. At the beginning of the Christian era, the religion of Rome was privately ridiculed and repudiated by nearly all statesmen and philosophers of the empire, although they publicly professed it on grounds of public policy. Seneca, a contemporary of Jesus, advised observance of rites appointed by law, on patriotic grounds. "All which things," he says, "a wise man will observe as being commanded by the laws, but not as being pleasing to the gods." Again he says: "All that ignoble rabble of gods which the superstition of ages has heaped up, we shall adore in such a way as to remember that their worship belongs rather to custom than to reality." Ridiculing the popular notions of the matrimonial relations of the deities, the same eminent philosopher says: "And what of this, that we unite the gods in marriage, and that not even naturally, for we join brothers and sisters? We marry Bellona to Mars, Venus to Vulcan, Salacia to Neptune. Some of them we leave unmarried, as though there were no match for them, which is surely needless, especially when there are certain unmarried goddesses, as Populonia, or Fulgora, or the goddess Rumina, for whom I am not astonished that suitors have been wanting." The prevailing skepticism of the times is well illustrated in a dialogue which Cicero introduces into his first Tusculan Disputation between M, which may be interpreted Marcus, and A, which may be translated Auditor: MARCUS: Tell me, are you not afraid of the three-headed Cerberus in the infernal regions, and the roaring of Cocytus, and the passage over Acheron, and Tantalus, dying with thirst, while water laves his chin, and Sisyphus, "Who sweats with arduous toil in vain The steepy summit of the mount to gain?" Perhaps you are also afraid of the inexorable judges, Minos and Rhadamanthus, because before them neither L. Crassus nor M. Antonius can defend you, and because appearing before Grecian judges, you will not be permitted to employ Demosthenes, but must plead for yourself before a very great crowd. All these things, perhaps, you fear, and therefore regard death as an eternal evil.
