Passage 10.29.10
Θησέως δὲ καὶ Πειρίθου τὴν λεγομένην φιλίαν ἐν ἀμφοτέραις ἐδήλωσεν Ὅμηρος ταῖς ποιήσεσι, καὶ Ὀδυσσεὺς μὲν πρὸς Φαίακας λέγων ἐστὶ καί νύ κʼ ἔτι προτέρους ἴδον ἀνέρας οὓς ἔθελόν περ, Θησέα Πειρίθοόν τε, θεῶν ἐρικυδέα τέκνα· Hom. Od. 11.631 foll. πεποίηται δὲ αὐτῷ καὶ ἐν Ἰλιάδι ὁ Νέστωρ ἄλλα τε ἐπὶ Ἀγαμέμνονος καὶ Ἀχιλλέως νουθεσίᾳ καὶ ἔπη τάδε εἰρηκώς· οὐ γάρ πω τοίους ἴδον ἀνέρας οὐδὲ ἴδωμαι οἷον Πειρίθοόν τε Δρύαντά τε ποιμένα λαῶν Καινέα τʼ Ἐξάδιόν τε καὶ ἀντίθεον Πολύφημον Θησέα τʼ Αἰγείδην ἐπιείκελον ἀθανάτοισιν. Hom. Il. 1.262 foll.
Homer has made clear the famous friendship between Theseus and Peirithous in both his poems. Odysseus, speaking among the Phaeacians, says: "And now I would have seen still earlier men, whom I wished indeed to behold—Theseus and Peirithous, illustrious sons of gods." (Homer, Odyssey 11.631ff.) Moreover, Nestor in the Iliad is portrayed as giving counsel to Agamemnon and Achilles, and there he speaks these words as well: "For never yet have I seen, nor shall I see, men such as Peirithous, Dryas, shepherd of the people, Kaineus, Exadios, godlike Polyphemus, and Theseus, son of Aegeus, resembling the immortals." (Homer, Iliad 1.262ff.)
