[174] _And Pegasus the steed._] Pegasus received its name from a well-known emblem, the horse of Poseidon: by which we are to understand an ark or ship. “By horses,” says Artemidorus, “the poets mean ships:” and hence it is that Poseidon is called Hippius; for there is a strict analogy between the poetical or winged horse on land, and a real ship in the sea. Hence it came that Pegasus was esteemed the horse of Poseidon (Neptune), and often named _scuphius_; a name which relates to a ship, and shows the purport of the emblem. The ark, we know, was preserved by divine providence from the sea, which would have overwhelmed it: and as it was often represented under this symbol of a horse, it gave rise to the fable of the two chief deities, Jupiter and Neptune, disputing about horses. BRYANT. To this we may add the still more remarkable fable of the dispute between Neptune and Pallas: when the former produces a horse, and the latter an olive-tree. “These notions,” observes the author of the Analysis, “arose from emblematical descriptions of the deluge, which the Grecians had received by tradition: but what was general they limited, and appropriated to particular places.” [175] _Old Nilus’ fountains._] Ωκεανου περι πηγας. Le Clerc remarks that “this derivation is absurd: as we do not talk of the fountains of the sea, but of rivers.” He adds, however, that “Hesiod more than once calls the ocean the river:” and this should have led him to perceive that it is in fact a river of which Hesiod speaks. The oceanic river was the Nile, which in very ancient times was called the Oceanus. [176] _Geryon rose._] One of the principal and most ancient settlements of the Amonians upon the ocean was at Gades; where a prince was supposed to have reigned, named Geryon. The harbour at Gades was a very fine one, and had several tor, or towers, to direct shipping: and as it was usual to imagine the deity to whom the temple was erected to have been the builder, this temple was said to have been built by Hercules. All this the Grecians took to themselves. They attributed the whole to Hercules of Thebes: and as he was supposed to conquer wherever he came, they made him subdue Geryon: and changing the tor or towers into so many head of cattle, they describe him as leading them off in triumph. Tor-keren signified a regal tower; and this being interpreted τρικαρηνος, this personage was in consequence described with three heads. BRYANT. Erythia, according to Pliny, is another name for Gades. [177] _In the deep-hollow’d cavern of a rock._] It is probable that at Arima in Cilicia there was an Ophite temple; which, like all the most ancient temples, was a vast cavern. Some emblematical sculpture of the serpent-deity may have given rise to the creation of this mythological prodigy. The Hydra had, probably, a similar origin.
