it expedient to fortify in a better way the thickly inhabited portion lying next the island of Ortygia, the circumference of which by itself equals that of an important city. Ortygia is connected to the mainland by a bridge, and [boasts of] the fountain Arethusa, which springs in such abundance as to form a river at once, and flows into the sea. They say that it is the river Alpheus[2288] which rises in the Peloponnesus, and that it flows through the land beneath the sea[2289] to the place where the Arethusa rises and flows into the sea. Some such proofs as these are given in support of the fact. A certain chalice having fallen into the river at Olympia was cast up by the springs of Arethusa; the fountain too is troubled by the sacrifices of oxen at Olympia. And Pindar, following such reports, thus sings, “Ortygia, revered place of reappearing[2290] of the Alpheus, The offset of renowned Syracuse.”[2291] Timæus[2292] the historian advances these accounts in like manner with Pindar. Undoubtedly if before reaching the sea the Alpheus were to fall into some chasm,[2293] there would be a probability that it continued its course from thence to Sicily, preserving its potable water unmixed with the sea; but since the mouth of the river manifestly falls into the sea, and there does not appear any opening in the bed of the sea there, which would be capable of imbibing the waters of the river, (although even if there were they could not remain perfectly fresh, still it might be possible to retain much of the character of fresh water, if they were presently to be swallowed down into a passage running below the earth which forms the bed of the sea,) it is altogether impossible; and this the water of Arethusa clearly proves, being perfectly fit for beverage; but [CAS. 271] that the flow of the river should remain compact through so long a course, not mixing with the sea until it should fall into the fancied channel, is entirely visionary; for we can scarcely credit it of the Rhone, the body of the waters of which remains compact during its passage through the lake, and preserves a visible course, but in that instance both the distance is short and the lake is not agitated by waves like the sea, but in this case of the Alpheus,[2294] where there are great storms and the waters are tossed with violence, the supposition is by no means worthy of attention. The fable of the chalice being carried over is likewise a mere fabrication, for it is not calculated for transfer, nor is it by any means probable it should be washed away so far, nor yet by such difficult passages. Many rivers, however, and in many parts of the world, flow beneath the earth, but none for so great a distance.—Still, although there may be no impossibility in this circumstance, yet the above-mentioned accounts are altogether impossible, and almost as absurd as the fable related of the Inachus: this river, as Sophocles[2295] feigns,
