This necessity is elegantly represented by Styx, the fatal river that can never be crossed back. And this deity it was, which Iphicrates the Athenian invoked in making a league; and because he roundly and openly avows what most others studiously conceal, it may be proper to give his own words. Observing that the Lacedæmonians were inventing and proposing a variety of securities, sanctions, and bonds of alliance, he interrupted them thus: “There may, indeed, my friends, be one bond and means of security between us; and that is, for you to demonstrate you have delivered into our hands, such things as that, if you had the greatest desire to hurt us, you could not be able.” Therefore, if the power of offending be taken away, or if, by a breach of compact, there be danger of destruction or diminution to the state or tribute, then it is that covenants will be ratified, and confirmed, as it were by the Stygian oath, whilst there remains an impending danger of being prohibited and excluded the banquet of the gods; by which expression the ancients denoted the rights and prerogatives, the affluence and the felicities, of empire and dominion. VI.—PAN, OR NATURE.[617] EXPLAINED OF NATURAL PHILOSOPHY. The ancients have, with great exactness, delineated universal nature under the person of Pan. They leave his origin doubtful; some asserting him the son of Mercury, and others the common offspring of all Penelope’s suitors. The latter supposition doubtless occasioned some later rivals to entitle this ancient fable Penelope; a thing frequently practised when the earlier relations are applied to more modern characters and persons, though sometimes with great absurdity and ignorance, as in the present case; for Pan was one of the ancientest gods, and long before the time of Ulysses; besides, Penelope was venerated by antiquity for her matronal chastity. A third sort will have him the issue of Jupiter and Hybris, that is, Reproach. But whatever his origin was, the Destinies are allowed his sisters. He is described by antiquity, with pyramidal horns reaching up to heaven, a rough and shaggy body, a very long beard, of a biform figure, human above, half brute below, ending in goat’s feet. His arms, or ensigns of power, are, a pipe in his left hand, composed of seven reeds; in his right a crook; and he wore for his mantle a leopard’s skin. His attributes and titles were the god of hunters, shepherds, and all the rural inhabitants; president of the mountains; and, after Mercury, the next messenger of the gods. He was also held the leader and ruler of the Nymphs, who continually danced and frisked about him, attended with the Satyrs and their elders, the Sileni. He had also the power of striking terrors, especially such as were vain and superstitious; whence they came to be called panic terrors.[618]
