Everybody knows what is related of the Marsi, people of Italy, and of the Psyllae, who possessed the secret of charming serpents. One would say, says St. Augustine,[163] that these animals understand the languages of the Marsi, so obedient are they to their orders; we see them come out of their caverns as soon as the Marsian has spoken. All this can only be done, says the same father, by the power of the malignant spirit, whom God permits to exercise this empire over venomous reptiles, above all, the serpent, as if to punish him for what he did to the first woman. In fact, it may be remarked that no animal is more exposed to charms, and the effects of magic art, than the serpent. The laws of the Twelve Tables forbid the charming of a neighbor's crops, _qui fruges excantasset_. Valerius Flaccus quotes authors who affirm that when the Romans were about to besiege a town, they employed their priests to evoke the divinity who presided over it, promising him a temple in Rome, either like the one dedicated to him in the besieged place, or on a rather larger scale, and that the proper worship should be paid to him. Pliny says that the memory of these evocations is preserved among the priests. If that which we have just related, and what we read in ancient and modern writers, is at all real, and produces the effects attributed to it, it cannot be doubted that there is something supernatural in it, and that the devil has a great share in the matter. The Abbot Trithemius speaks of a sorceress who, by means of certain beverages, changed a young Burgundian into a beast. Everybody knows the fable of Circe, who changed the soldiers or companions of Ulysses into swine. We know also the fable of the Golden Ass, by Apuleius, which contains the account of a man metamorphosed into an ass. I bring forward these things merely as what they are, that is to say, simply poetic fictions. But it is very credible that these fictions are not destitute of some foundation, like many other fables, which contain not only a hidden and moral sense, but which have also some relation to an event really historical: for instance, what is said of the Golden Fleece carried away by Jason; of the Wooden Horse, made use of to surprise the city of Troy; the Twelve Labors of Hercules; the metamorphoses related by Ovid. All fabulous as those things appear in the poets, they have, nevertheless, their historical truth. And thus the pagan poets and historians have travestied and disguised the stories of the Old Testament, and have attributed to Bacchus, Jupiter, Saturn, Apollo, and Hercules, what is related of Noah, Moses, Aaron, Samson, and Jonah, &c.
