“When the dark singer, / the sphinx, was in your country, did you speak / word of deliverance to its citizens? / And yet the riddle’s answer was not the province / of a chance comer. It was a prophet’s task / and plainly you had no such gift of prophecy / from birds nor otherwise from any God / to glean a word of knowledge. But I came, / Oedipus, who knew nothing, and I stopped her. / I solved the riddle by my wit alone” (Oedipus Rex, Oedipus speaking to Teiresias, 391-397).
