<head>II. On the Voyage of Ulysses, especially in the neighbourhood of Sicily</head>It is not like Homer to build an empty narrative full of marvels on no basis of truth.
For naturally the fact is that one makes falsehood more credible if one mixes a little truth with it,
as Polybius also says when he undertakes to deal with the wanderings of Ulysses.
Polybius is right in his notion about the wanderings of Ulysses.
For he says that Aeolus, the man who gave sailing directions for the seas near the Straits, which have a current setting both ways and are difficult to pass owing to the tides, was supposed to be the dispenser of the winds and a king, just as Danaus, who first showed them how to make the reservoirs in <a class="linkToPlace" target="_blank" href="/place?placename=Argos&groupId=361&placeId=689">Argos</a>, and Atreus who discovered that the motion of the sun was contrary to that of the heavens, and seers and those who practised divination from sacrifices, were styled kings, and the Egyptian priests, and the Chaldaeans and the Magi, who were distinguished from other men by some special science, enjoyed in early times peculiar precedence and honour, and just as each of the gods is honoured as the author of some useful invention.
Having thus prepared his way, he does not allow us to treat Aeolus and the whole of the wanderings of Ulysses as mythical, but he says, that while some mythical elements have been added, as in the case of the Trojan war, the main statements about <a class="linkToPlace" target="_blank" href="/place?placename=Sicily&groupId=973&placeId=1724">Sicily</a> correspond to those of the other writers who treat of the local history of <a class="linkToPlace" target="_blank" href="/place?placename=Italy&groupId=656&placeId=1199">Italy</a> and <a class="linkToPlace" target="_blank" href="/place?placename=Sicily&groupId=973&placeId=1724">Sicily</a>.
Neither does he applaud the dictum of Eratosthenes that we may find out where Ulysses travelled when we find the cobbler who sewed the bag of the winds.
And it is, he says, quite in accordance with the facts about the Scyllaean rock and the method of fishing for sword-fish, when he says about Scylla—<quote><l>Her heads, with which the ravening monster dives</l><l>In quest of dolphins, dog-fish, or of prey</l><l>More bulky.</l></quote>
For when the tunnies swimming in shoals along the Italian coast are carried out of their course and are unable to approach the Sicilian coast they fall a prey to larger animals, such as dolphins, sharks, and other marine monsters.
By preying on them the sword-fish (galeotae), also called xiphiae and sea-dogs, are fattened.
For in this case and in that of the rising of the <a class="linkToPlace" target="_blank" href="/place?placename=Nile&groupId=794&placeId=449">Nile</a> and other waters, the same thing happens as in the case of forest fires. The wild animals collect to escape from the fire or the water and are devoured by the more powerful ones.
