When Odysseus returns to Ithaka he must undergo suffering at the hands of the suitors to justify their murders. When he and Athena make their plans in book 13, some audiences might wonder why he does not get help from allies on the mainland. Never fear, Porphyry is here to explain.
Porphyry, Hom. Quest. ad Od 13.387
“Why doesn’t Odysseus just send to Nestor and Menelaos to get an army? Because it seemed most unjust to him to impose a war on the rest of the citizens who were guilty of nothing. For he had learned from his mother in Hades that the public rights were being guarded for Telemachus and that he would avenge the transgressive suitors even on his own. And, also, if the suitors knew [that an army was coming], they would escape without paying a penalty.”
πῶς οὐ πρὸς Νέστορα καὶ Μενέλαον μετέρχεται στρατιὰν λαβεῖν; τάχα ὅτι τοῖς λοιποῖς πολίταις οὐδὲν αἰτίοις οὖσι πόλεμον ἐπάγειν ἀδικώτατον ἔδοξε. μεμάθηκε γὰρ καὶ παρὰ τῆς μητρὸς ἐν ῞Αιδου τὰς δημοσίας Τηλεμάχῳ φυλασσομένας τιμάς, καὶ ὅτι τοὺς τρυφῶντας μνηστῆρας τιμωρήσεται καὶ καθ’ ἑαυτόν. οἵ τε μνηστῆρες, εἰ ᾔσθοντο, ἔφυγον ἂν μὴ δόντες δίκην.
