This is the last of the events of the age of heroes, when so much must be fable, though there may be a germ of historical truth which no one can make out among the old tales that had come from the East, and the like of which may be found among the folk-lore of all nations.  These are the most famous of the stories, because they joined all Greeks together, and were believed in by all Greeks alike in their main circumstances; but every state had its own story, and one or two may be told before we end this chapter of myths, because they are often heard of, and poetry has been written about some of them.
