A Poetic Initiation Scene in Hipponax?

In a note in Heph. 3.1 ( = Hipponax Testim. 21 Dg), Choeroboscus relates several etymologies of the term "iambos." The first is the familiar derivation from the mythical Iambe, the servant of the King Celeus of Elusis, who cheered up the grieving Demeter by mocking her. This story, well known to us from the Homeric Hymn to Demeter (198-211), functioned as an ation of the ritual jesting and abuse practiced at the various festivals of Demeter, and, by extension, of the poetic genre known as iambos.1
