2. σφυρόν in the Iliad
εὐφυέες κνῆμαί τε ἰδὲ σφυρὰ κάλ’ ὑπένερθε
χερμαδίῳ γὰρ βλῆτο παρὰ σφυρὸν ὀκριόεντι
κνήμην δεξιτερήν· βάλε δὲ Θρῃκῶν ἀγὸς ἀνδρῶν
Πείρως Ἰμβρασίδης ὃς ἄρ’ Αἰνόθεν εἰληλούθει.
ἀμφοτέρω δὲ τένοντε καὶ ὀστέα λᾶας ἀναιδὴς
ἄχρις ἀπηλοίησεν· ὃ δ’ ὕπτιος ἐν κονίῃσι
Diores is not the prominent figure in the Iliad that Menelaos is.  But he is nevertheless important at the close of Book IV as a symbol of the destruction of war. The last lines of the book present the image of his corpse lying beside the corpse of his killer.  The two warring leaders, ironically united in death, are emblematic of all those who die. The last five lines of the book, in fact, stand back from the action and emphasize explicitly the significance of the image as a paradigm of war. 
δησάμενος τελαμῶνι παρὰ σφυρὸν ἀμφὶ τένοντας.
Patroklos’ death has the most important consequences of any event in the Iliad. It marks the turning point in the story, spurring Achilles’ entrance into battle and thereby precipitating the concluding events of the poem.
ἀμφὶ δέ μιν σφυρὰ τύπτε καὶ αὐχένα δέρμα κελαινὸν.
This passage, free from any violence, seems at first to have nothing in common with the themes and imagery of the other passages where the noun appeared. Yet the details of this description are significant, for they form an important symbolic image, one that presages exactly the circumstances of Hektor’s death. The passage describes only the hero’s neck and ankles, his αὐχήν and σφυρόν as the oxhide shield clashes against them. And it is the αὐχήν, in the end, where Achilles makes the fatal wound, and the σφυρόν by which Achilles drags the corpse (XXII 396–397).
ἐς σφυρὸν ἐκ πτέρνης, βοέους δ’ ἐξῆπτεν ἱμάντας.
The ox-hide thongs drawn through Hektor’s ankles recall the image of the ox-hide shield hitting his ankles in Book VI. All the details of his death and mutilation have resonances in this earlier passage.
καί ἑ θοῶς οὔτησε κατὰ σφυρόν. Αἶψα δ’ ἀνῖαι
δῦσαν ὑπὸ κραδίην·
Though Quintus is a writer of quite late times, he certainly adopted both his language and his subject matter from the epic cycles. His diction is very close to that of the Homeric poems; and his narrative covers the same material as the Aithiopis, the Iliupersis and the Little Iliad do. And so it is likely that he drew the details of Achilles’ death from earlier traditions. The connection that the fatal ankle wound establishes with the deaths of Hektor and Patroklos in the Iliad makes sense thematically, and is indeed what one might expect to follow from the symbolic and thematic implications in the Iliad. This late attestation lends further credence to the significance of σφυρόν in the Iliad.
