the undertaking was soon relinquished the stately remains of unfinished walls and towers attracted the notice of all who sailed through the straits of the Hellespont. 21 15 (return) [ See an admirable dissertation of M. d’Anville upon the Hellespont or Dardanelles, in the Mémoires tom. xxviii. p. 318—346. Yet even that ingenious geographer is too fond of supposing new, and perhaps imaginary _measures_, for the purpose of rendering ancient writers as accurate as himself. The stadia employed by Herodotus in the description of the Euxine, the Bosphorus, &c., (l. iv. c. 85,) must undoubtedly be all of the same species; but it seems impossible to reconcile them either with truth or with each other.] 16 (return) [ The oblique distance between Sestus and Abydus was thirty stadia. The improbable tale of Hero and Leander is exposed by M. Mahudel, but is defended on the authority of poets and medals by M. de la Nauze. See the Académie des Inscriptions, tom. vii. Hist. p. 74. elem. p. 240. Note: The practical illustration of the possibility of Leander’s feat by Lord Byron and other English swimmers is too well known to need particularly reference—M.] 17 (return) [ See the seventh book of Herodotus, who has erected an elegant trophy to his own fame and to that of his country. The review appears to have been made with tolerable accuracy; but the vanity, first of the Persians, and afterwards of the Greeks, was interested to magnify the armament and the victory. I should much doubt whether the _invaders_ have ever outnumbered the _men_ of any country which they attacked.] 1711 (return) [ Gibbon does not allow greater width between the two nearest points of the shores of the Hellespont than between those of the Bosphorus; yet all the ancient writers speak of the Hellespontic strait as broader than the other: they agree in giving it seven stadia in its narrowest width, (Herod. in Melp. c. 85. Polym. c. 34. Strabo, p. 591. Plin. iv. c. 12.) which make 875 paces. It is singular that Gibbon, who in the fifteenth note of this chapter reproaches d’Anville with being fond of supposing new and perhaps imaginary measures, has here adopted the peculiar measurement which d’Anville has assigned to the stadium. This great geographer believes that the ancients had a stadium of fifty-one toises, and it is that which he applies to the walls of Babylon. Now, seven of these stadia are equal to about 500 paces, 7 stadia = 2142 feet: 500 paces = 2135 feet 5 inches.—G. See Rennell, Geog. of Herod. p. 121.
