For in the fleet of twelve hundred vessels he has represented the ships of the Boeotians as having one hundred and twenty men each, and those of Philoctetes as having fifty,[*](Hom. B 510, 719.) indicating, it seems to me, the largest and the smallest ships; at any rate, no mention as to the size of any others is made in the Catalogue of Ships. But that all on board were at once rowers and fighting men he has shown in the case of the ships of Philoctetes; for he represents all the oarsmen as archers. And it is not likely that many supernumeraries sailed with the expedition, apart from the kings and those highest in office, especially as they were to cross the open sea with all the equipment of war, and, furthermore, had boats which were not provided with decks, but were built after the early style, more like pirate-boats.
In any event, if one takes the mean between the largest ships and the smallest, it is clear that not a large number of men went on the expedition, considering that they were sent out from all Hellas in common.[*](The number would be 102,000, i.e. 1,200 ships at 85 men each.)
