’Aυαγυώρισις γàρ διόλov, says Aristotle of the Odyssey,2 and throughout the poem's second half, with which we are here concerned, there is indeed a series of progressive recognitions as Odysseus reveals himself to Telemachos, Eurykleia, Eumaios, the suitors, Penelope and finally Laertes. So the importance of the opposite is not surprising; without concealment and deception there could be no eventual recognition. Concealment is of course necessary if Odysseus is to survive in the face of so many enemies, as Athena tells him (13. 307–10). But in addition, in any work of imaginative literature, so long as the reader or audience is aware of the truth, concealment and unperceived identity open the door to all sorts of half-truths and ironies – possibilities most obviously explored in tragedy and later comedy, but also made use of in the Odyssey. The irony which may be inherent in the arrival of the ‘nameless stranger’ has been most thoroughly explored by Fenik;3 here we examine a further implication.
