Contemporary with Epicurus and Zeno and Pyrrho, too, was Evêmeros (Euhemerus), whose peculiar propaganda against Godism seems to imply theoretic atheism. As an atheist he was vilified in a manner familiar to modern ears, the Alexandrian poet Callimachus labelling him an "arrogant old man vomiting impious books." [716] His lost work, of which only a few extracts remain, undertook to prove that all the Gods had been simply famous men, deified after death; the proof, however, being by way of a fiction about old inscriptions found in an imaginary island. [717] As above noted, [718] the idea may have been borrowed from skeptical Phoenicians, the principle having already been monotheistically applied by the Bible-making Jews, [719] though, on the other hand, it had been artistically and to all appearance uncritically acted on in the Homeric epopees. It may or may not then have been by way of deliberate or reasoning Evêmerism that certain early Greek and Roman deities were transformed, as we have seen, into heroes or hetairai. [720] In any case, the principle seems to have had considerable vogue in the later Hellenistic world; but with the effect rather of paving the way for new cults than of setting up scientific rationalism in place of the old ones. Quite a number of writers like Palaiphatos, without going so far as Evêmeros, sought to reduce myths to natural possibilities and events, by way of mediating between the credulous and the incredulous. [721] Their method is mostly the naïf one revived by the Abbé Banier in the eighteenth century of reducing marvels to verbal misconceptions. Thus for Palaiphatos the myth of Kerberos came from the facts that the city Trikarenos was commonly spoken of as a beautiful and great dog; and that Geryon, who lived there, had great dogs called Kerberoi; Actæon was "devoured by his dogs" in the sense that he neglected his affairs and wasted his time in hunting; the Amazons were shaved men, clad as were the women in Thrace, and so on. [722] Palaiphatos and the Herakleitos who also wrote De Incredibilibus agree that Pasiphae's bull was a man named Tauros; and the latter writer similarly explains that Scylla was a beautiful hetaira with avaricious hangers-on, and that the harpies were ladies of the same profession. If the method seems childish, it is to be remembered that as regards the explanation of supernatural events it was adhered to by German theologians of a century ago; and that its credulity in incredulity is still to be seen in the current view that every narrative in the sacred books is to be taken as necessarily standing for a fact of some kind.
