It is noticeable that there is no mention of these Heraclidae or their invasion in Homer or Hesiod.
Aristarchus says he lived about the period of the Ionian emigration; this happened sixty years after the return of the Heraclidae.
But the affair of the Heraclidae took place eighty years after the destruction of Troy.
