Aristotle'sPolitics1336b20–2 (cited below) proves that in the fourth centuryb.c. there was more than one type of occasion for the presentation of iambic poetry. No surviving ancient testimony describes directly the circumstances of performance of literary iambus in the archaic period. Heraclitus' text which comes from the turn of the sixth and fifth centuriesb.c. suggests that Archilochus' poems, like Homer's, were presented during poetic competitions, but it does not follow that Heraclitus had in mind iambic compositions of the Parian poet.
