further; but this does not abridge his power of proceeding to a greater diſtance in that ſpace of time. It ſhould alſo be obſerved, that, although the diſtance between Attica and Lemnos is conſider able, the Lemnians guarded their promiſe by reſtricting the voyage to be performed by a northerly wind.
Again, the diſtance between Elmum and the neareſt point of Lemnos is, by Mr. D'Anville's map, 420 Olympic ſtadia, or more than 52 Greek miles; and according to Mr. Rochette's map, at leaſt 49 miles. Theſe diſtances approach much nearer to the calculation of Ptolemy than to that of Mr. Rennel; and indeed this inſtance proves nothing, as it does not appear that Miltiades might not have gone further, had he been ſo inclined.
Mr. Rennel next inſtances the fleet of Xerxes, which, he ſays, failed from the Euripus to Phalerus, a port in Attica, in three days, which he ſays is 06 Greek miles, or 32 Greek miles each day: The words of Herodotus are, "that Xerxes, after having viewed the dead bodies of the Lacedæmonians ſlain at Thermopylæ, paſſed over from Trachis to Hiſtiæa, and after three days ſtay ſailed through the Euripus, and in three days arrived at Phalerus." The diſtance from Hiſtiæa to Phalerus through the Euripusis, according to Mr. D'Anville, 179 Greek miles, and according to Mr. Rochette's map, 174 Greek miles; which gives, according to the loweſt of theſe calculations, 58 Greek miles for each day's ſail, inſtead of 32, according to Mr. Rennel. If we conſider the vaſt fleet which performed this voyage, and the narrow ſtraits through which they failed, we may be juſtly ſurprifed they were ſo expeditious. But a fleet of 1000 ſhips is no proper inſtance to prove how far ſhips in general may fail in a given time.
