For the life of the poet Ion we have more certain dates than for most of the Other writers of the fifth century. He produced his first tragedy in the 82nd Olympiad, 452–448 B.C., another in the year of the archon Epameinon 429/428 B.C. —after the death of Perikles and when the revolt of Lesbos was imminent—and his death is fixed for us by a passage in the Peace of Aristophanes, which we may well call an obituary, in summer 422 or even in winter 422/421 B.C. The approximate date of his birth we learn from his own words in a story preserved by Plutarch, and deriving no doubt from the book to which later librarians gave the title 'Επι7dgr;ημίαι or 'Υπομνήμαтα: 5 συδειπνσαι δè тι Κίμωνί ησιν Ἴων πανάπασιν μειράκιον ἢκων ες 'Aθήνας Χίου παρà Ααομέδονтι. Hence he was about fifteen years of age when he first came to Athens, apparently in order to get his higher education there—a fact which seems significant of the position which Athens had won for herself by the foundation of the Delian League. At the same time this fact clearly indicates that his father Orthomenes, whom they called Xuthos, had whole-heartedly espoused the cause of Athens. He bequeathed his loyalty to his son Ion, who adhered to Athens through all vicissitudes of fortune, and he in his turn bequeathed it to his son Tydeus, who paid for it with his life.
