Implicitly challenging the Corinthian to tell him that he is not the natural child of Polybos and Merope, Oidipous raises the very same question that once propelled him to Delphi. His admission of the possibility of error implies awareness of the distinction between biological (γεννετῶν) and adoptive parents. That he himself makes the distinction suggests that it was not unreasonable for him to be expected to make sense of the prophecy he received from the Pythia. The same might be said for Athens; it can be expected to make sense of Dephi’s words to the Spartan embassy about which Athens has received reports. [Mipd] [Gt-a]
