Homer. Il. 6.332 “But come now, enter in, and sit thee upon this chair,  my brother, since above all others has trouble encompassed thy heart because of shameless me, and the folly of Alexander; on whom Zeus hath brought an evil doom, that even in days to come we may be a song for men that are yet to be.” Homer. Od. 8.550 ״So that old man spoke, and these things the god will haply bring to pass, or will leave unfulfilled, as may be his good pleasure. But come, now, tell me this and declare it truly: whither thou hast wandered and to what countries of men thou hast come; tell me of the people and of their well-built cities,  both of those who are cruel and wild and unjust, and of those who love strangers and fear the gods in their thoughts. And tell me why thou dost weep and wail in spirit as thou hearest the doom of the Argive Danaans and of Ilios. This the gods wrought, and spun the skein of ruin  for men, that there might be a song for those yet to be born״. & so they live and die in order to be sung.
