Apollodorus, in his work On the Catalogue of Ships
, goes on to say to this effect, that all the allies of the Trojans from Asia were enumerated by the poet as being inhabitants of the peninsula, of which the narrowest isthmus is that between the innermost recess at Sinope and Issus. And the exterior sides of this peninsula, he says, which is triangular in shape, are unequal in length, one of them extending from Cilicia to the Chelidonian Islands, another from the Chelidonian Islands to the mouth of the Euxine, and the third thence back to Sinope. Now the assertion that the allies were alone those who lived in the peninsula can be proved wrong by the same arguments by which I have previously shown that the allies were not alone those who lived this side the Halys River.1
For just as the places round Pharnacia, in which, as I said, the Halizoni lived, are outside the Halys River, so also they are outside the isthmus, if indeed they are outside the narrows between Sinope and Issus; and not outside these alone, but also outside the true narrows between Amisus and Issus, for he too incorrectly defines the isthmus and its narrows, since he substitutes the former for the latter. But the greatest absurdity is this, that, after calling the peninsula triangular in shape, he represents the "exterior sides" as three in number; for when he speaks of the "exterior sides" he seems privily to exclude the side along the narrows, as though this too were a side, but not "exterior" or on the sea. If, then, these narrows were so shortened that the exterior side ending at Issus and that ending at Sinope lacked but little of joining one another, one might concede that the peninsula should be called triangular; but, as it is, since the narrows mentioned by him leave a distance of three thousand stadia between Issus and Sinope, it is ignorance and not knowledge of chorography to call such a four-sided figure triangular. Yet he published in the metre of comedy2
a work on chorography entitled A Description of the Earth
. The same ignorance still remains even though one should reduce the isthmus to the minimum distance, I mean, to one-half of the whole distance, as given by those who have most belied the facts, among whom is also Artemidorus, that is, fifteen hundred stadia; for even this does contract the side along the narrows enough to make the peninsula a triangular figure. Neither does Artemidorus correctly distinguish the exterior sides when he speaks of "the side that extends from Issus as far as the Chelidonian Islands," for there still remains to this side the whole of the Lycian coast, which lies in a straight line with the side he mentions, as does also the Peraea of the Rhodians as far as Physcus. And thence the mainland bends and begins to form the second, or westerly, side extending as far as the Propontis and Byzantium.
