The laſt diſtance I ſhall cite from this author is from Lacedæmon to Crete, which is counted one day's fail, and is nearly 500 ſtadia. The average of the above diſtances is about 470 ſtadia in the courſe of twelve hours, or nearly 40 ſtadia, or 5 Greek miles, every hour.
Xenophon in his Anabaſis ſays, that he failed from Cotyora to Harmene in two days and one night. This diſtance by ſea, if meaſured round Cape Boona, amounts to 1422 ſtadia, or 162.765 Engliſh miles, by D'Anville's map, which is equal to nearly 500 ſtadia daily. By Arrowſmith's chart it is 167 Engliſh miles, equal to 1460 ſtadia nearly, or about 487 ſtadia daily.
Xenophon ſays again, that the Greeks failed from Harmene, or Sinope, to Heraclea in two days, which is about 1800 ſtadia; but the ſhips they employed were probably not the beſt ſailers, as he ſays, that a trireme galley would, in a very long day, fail from Byzantium to Heraclea. This, according to Arrowſmith's chart, is 1150 ſtadia, or 131 Engliſh miles nearly, which, if we reckon ſixteen hours to the day, would be nearly 8¼ miles per hour. Xenophon however eſteems this an extraordinary exertion, and ſuch as required, no doubt, a favourable wind; and then, by the joint power of fails and oars, ſuch a diſtance is not unlikely to be accompliſhed.
Tournefort, though embarraſſed with the company of many veſſels, and bad failors, Went 80 miles in a day on this coaſt, with the greateſt eaſe, and even by four in the afternoon; and failed ſeventy miles more that night. He accounts 50 miles a ſmall diſtance for a day's ſail, and 60 miles as a very moderate one.
