There is a pattern of onomatopoeia built into the name Itylos = ´Itulos, as derivative of ´Itus (Ἴτυς), a name of the son of the unfortunate mythical woman who was turned into a nightingale. The doubling of this name produces a “tweeting” effect, as in Aeschylus Agamemnon 1144: Ἴτυν Ἴτυν στένουσ᾿ ‘[the nightingale] mourning “´Itun ´Itun”’; also Sophocles Electra 148: ἃ Ἴτυν αἰὲν Ἴτυν ὀλοφύρεται ‘who keeps on mourning “´Itun ´Itun”’.
