In the first book of the Iliad, Nestor attempts to intervene in the conflict between Achilles and Agamemnon. He eventually tells both men to simmer down—Achilles should act insubordinately and Agamemnon shouldn’t take Briseis. Neither of them listen to him. The reason—beyond the fact that neither of them are in a compromising state of mind—may in part be because of the story Nestor tells.
“But listen to me: both of you are younger than me; for long before have I accompanied men better than even you and they never disregarded me. For I never have seen those sort of men since, nor do I expect to see them; men like Perithoos and Dryas, the shepherd of the host, and Kaineus and Exadios and godly Polyphemos and Aigeus’ son Theseus, who was equal to the gods; indeed these were the strongest of mortal men who lived—they were the strongest and they fought with the strongest, mountain-inhabiting beasts, and they destroyed them violently. And I accompanied them when I left Pylos far off from a distant land when they summoned me themselves; and I fought on my own. No one could fight with them, none of those mortals who now are on the earth. Even they listened to my counsel and heeded my speech.”
ἀλλὰ πίθεσθ’· ἄμφω δὲ νεωτέρω ἐστὸν ἐμεῖο·
ἤδη γάρ ποτ’ ἐγὼ καὶ ἀρείοσιν ἠέ περ ὑμῖν
ἀνδράσιν ὡμίλησα, καὶ οὔ ποτέ μ’ οἵ γ’ ἀθέριζον.
οὐ γάρ πω τοίους ἴδον ἀνέρας οὐδὲ ἴδωμαι,
οἷον Πειρίθοόν τε Δρύαντά τε ποιμένα λαῶν
Καινέα τ’ ᾿Εξάδιόν τε καὶ ἀντίθεον Πολύφημον
Θησέα τ’ Αἰγεΐδην, ἐπιείκελον ἀθανάτοισιν·
κάρτιστοι δὴ κεῖνοι ἐπιχθονίων τράφεν ἀνδρῶν·
κάρτιστοι μὲν ἔσαν καὶ καρτίστοις ἐμάχοντο
φηρσὶν ὀρεσκῴοισι καὶ ἐκπάγλως ἀπόλεσσαν.
καὶ μὲν τοῖσιν ἐγὼ μεθομίλεον ἐκ Πύλου ἐλθὼν
τηλόθεν ἐξ ἀπίης γαίης· καλέσαντο γὰρ αὐτοί·
καὶ μαχόμην κατ’ ἔμ’ αὐτὸν ἐγώ· κείνοισι δ’ ἂν οὔ τις
τῶν οἳ νῦν βροτοί εἰσιν ἐπιχθόνιοι μαχέοιτο·
καὶ μέν μευ βουλέων ξύνιεν πείθοντό τε μύθῳ·
Ancient commentators praise Nestor elsewhere for his ability to apply appropriate examples in his persuasive speeches:
Schol. Ad Il. 23.630b ex. 1-6: “[Nestor] always uses appropriate examples. For, whenever he wants to encourage someone to enter one-on-one combat, he speaks of the story of Ereuthaliôn (7.136-56); when he wanted to rouse Achilles to battle, he told the story of the Elean war (11.671¬–761). And here in the games for Patroklos, he reminds them of an ancient funeral contest.”
ex. ὡς ὁπότε κρείοντ'<—᾿Επειοί>: ἀεὶ οἰκείοις παραδείγμασι χρῆται· ὅταν μὲν γάρ τινα ἐπὶ μονομάχιον ἐξαναστῆσαι θέλῃ, τὰ περὶ ᾿Ερευθαλίωνα (sc. Η 136—56) λέγει, ὅταν δὲ ᾿Αχιλλέα ἐπὶ τὴν μάχην, τὰ περὶ τὸν ᾿Ηλειακὸν πόλεμον (sc. Λ 671—761)·
καὶ ἐν τοῖς ἐπὶ Πατρόκλῳ ἄθλοις παλαιοῦ ἐπιταφίου μέμνηται ἀγῶνος.
The scholia also assert that such use of stories from the past is typical of and appropriate to elders:
Schol. ad Il. 9.447b ex. 1-2 : “The elderly are storytellers and they persuade with examples from the past. In other cases, the tale assuages the anger…”
μυθολόγοι οἱ γέροντες καὶ παραδείγμασι παραμυθούμενοι. ἄλλως τε ψυχαγωγεῖ τὴν ὀργὴν ὁ μῦθος.
