But the greatest absurdity is this, that after having said that the peninsula was of a triangular shape, he speaks of three _exterior_ sides. For in speaking of _exterior_ sides, he seems to except the line of the isthmus itself, considering it still a side, although not an _exterior_ side, from its not being upon the sea. But if this line were so shortened that the extremities of the (_exterior_) sides falling upon Issus and Sinope nearly coincided, the peninsula might in that case be said to be of a triangular shape; but as his own line (from Sinope to Issus) is 3000 stadia in length, it would be ignorance, and not a knowledge of chorography, to call such a four-sided figure a triangle. Yet he published a work on Chorography, in the metre of comedy, (Iambic metre,) entitled “The Circuit of the Earth.” He is still liable to the same charge of ignorance, even if we should suppose the isthmus to be contracted to its least dimensions, and follow writers who erroneously estimate the distance at one-half of the sum, namely 1500 stadia, to which it is reduced by Artemidorus; but even this would not by any means reduce the thus contracted space to the figure of a triangle. Besides, Artemidorus has not correctly described the exterior sides; one side, he says, extends from Issus to the Chelidoniæ islands, although the whole Lycian coast, and the country opposite to Rhodes as far as Physcus, lies in a straight line with, and is a continuation of it; the continent then makes a bend at Physcus, and forms the commencement of the second or western side, extending to the Propontis and Byzantium. 23. Ephorus had said that this peninsula was inhabited by sixteen tribes, three of which were Grecian, and the rest barbarous, with the exception of the mixed nations; he placed on the sea-coast Cilicians, Pamphylians, Lycians, Bithynians, Paphlagonians, Mariandyni, Troes, and Carians; and in the interior, Pisidians, Mysians, Chalybes, Phrygians, and Milyæ.[275] Apollodorus, when discussing this position, says there is a seventeenth tribe, the Galatians, who are more recent than the time of Ephorus; that of the sixteen tribes mentioned, the Greeks were not settled (in the peninsula) at the period of the Trojan war, and that time has produced great intermixture and confusion among the barbarous nations. Homer, he continues, recites in his Catalogue the Troes, and those now called Paphlagonians, Mysians, Phrygians, Carians, Lycians, Meionians, instead of Lydians and other unknown people, as Halizoni and Caucones; nations besides not mentioned in the Catalogue but elsewhere, as Ceteii, Solymi, the Cilicians from the plain of Thebe, and Leleges. But the Pamphylians, Bithynians, Mariandyni, Pisidians, and Chalybes, Milyæ, and Cappadocians are nowhere mentioned by the poet; some because they did not then inhabit these places, and some because they were surrounded by other tribes, as Idrieis and Termilæ by Carians, Doliones and Bebryces by Phrygians.
