The Jesuit Tournemine suggests the following explanation of the story:--He says, that the aborigines of Attica, being conquered by the Pelasgians, learned from them the art of navigation, which they turned to account by becoming pirates. Cecrops, bringing a colony from Saïs, in Egypt, tried to abolish this barbarous custom, and taught them a more civilized mode of life; and, among other things, he showed them how to till the earth, and to raise the olive, for the cultivation of which he found the soil very favorable. He also introduced the worship of Minerva, or Athena, as she was called, a Goddess highly honored at Saïs, and to whom the olive tree was dedicated. Her the Athenians afterwards regarded as the patroness of their city, which they called after her name. Athens becoming famous for its olives, and, considerable profit arising from their cultivation, the new settlers attempted to wean the natives from piracy, by calling their attention to agricultural pursuits. To succeed in this, they composed a fable, in which Neptune was said to be overcome by Minerva; who, even in the judgment of the twelve greater deities, had found out something of more utility than he. This fable Tournemine supposes to have been composed in the ancient language of the country, which was the Phrygian, mingled with many Phœnician words; and, as in those languages the same word signifies either a ship or a horse, those who afterwards interpreted the fable, took the word in the latter signification, and spoke of a horse instead of a ship, which was really the original emblem employed in the fiction.
Vossius thinks that the fable originated in a dispute between the sailors of Athens, who acknowledged Neptune for their chief, and the people, who followed the Senate, governed by Minerva. The people prevailed, and a life of civilization, marked by attention to the pursuits of agriculture, was substituted for one of piracy; which gave occasion for the saying, that Minerva had overcome Neptune.
With reference to the intrigues and lustful actions attributed to the various Deities by Arachne in the delineations on her embroidery, we may here remark, by way of elucidating the origin of these stories in general, that, in early times, when the earth was sunk in ignorance and superstition, and might formed the only right in the heathen world, where a king or petty chieftain demanded the daughter of a neighbor in marriage, and met with a refusal, he immediately had recourse to arms, to obtain her by force. Their standards and ships, on these expeditions, carrying their ensigns, consisting of birds, beasts, or fabulous monsters, gave occasion to those who described their feats of prowess to say, that the ravisher had changed himself into a bull, an eagle, or a lion, for the purpose of effecting his object. The kings and potentates of those days, being frequently called Jupiter, Apollo, Neptune, etc., and the priests of the Gods so named often obtaining their ends by assuming the names of the Divinities they served, we can account the more easily for the number of intrigues and abominable actions, attended by changes and transformations, which the poets and mythologists attribute to many of the Deities.
