Passage 9.41.5
καὶ ἐν Πηνελόπης δώροις---ἄλλους τε γὰρ τῶν μνηστήρων δῶρα καὶ Εὐρύμαχον διδόντα Πηνελόπῃ πεποίηκεν--- ὅρμον δʼ Εὐρύμαχος πολυδαίδαλον αὐτίκʼ ἔνεικε χρύσεον, ἠλέκτροισιν ἐερμένον, ἠέλιον ὥς· Hom. Od. 18.295 Ἐριφύλην δὲ οὐ χρυσῷ καὶ λίθοις ποικίλον δέξασθαί φησιν ὅρμον. οὕτω τὸ εἰκὸς τῷ σκήπτρῳ πρόσεστιν εἶναι μόνον ποίημα Ἡφαίστου.
Also among Penelope's gifts—for he has depicted other suitors also, and Eurymachus bestowing gifts upon Penelope—Eurymachus straightway brought her a golden necklace elaborately wrought, set with amber, as radiant as the sun (Hom. Od. 18.295). He claims, moreover, that Eriphyle's necklace was not adorned with gold and jewels. Thus it seems likely that only the sceptre was fashioned by Hephaestus.
