The expression “unspeakable of unspeakables” pertains even better to parricide and incest than to murder and regicide. Thus, the Chorus inadvertently folds crimes of which it is not aware into the mix with crimes of which it knows Delphi already to have spoken. The audience, however, knows that Delphi predicted even the more unspeakable of unspeakables. The crimes, then, are not in fact unspeakable. Delphi is capable of speaking about any subject, no matter how abhorrent. The fact that Delphi spoke about the incest and murder even before they occurred suggests, however, a curative or–better–preventive function for prophecy. [Apcmas] [Mi] [Mw]
