Πηλείδην ἐκ̣ό̣μιζε πόδας ταχύν, ἔξοχον ἀνδρῶν,
παῖδ᾿ ἔτ᾿ ἐόν[τ᾿·] οὐ γάρ μιν ἀρηΐφιλος Μενέλαος
νίκησ᾿ οὐδέ τις ἄλλος ἐπιχθονίων ἀνθρώπων
μνηστεύων Ἑλένην, εἴ μιν κίχε παρθένον οὖσαν
οἴκαδε νοστήσας ἐκ Πηλίου ὠκὺς Ἀχιλλεύς.
Cheiron in woody Peleion was rearing the son of Peleus, swift-footed, best of
men, [but] still a child; for neither Menelaus who is dear to Ares nor some other
among mortal men would have won in marrying Helen, if swift Achilles found
her still unmarried, after returning home from Peleion. 
This testimony may be an argumentum ex silentio demonstrating that archaic epic was ‘familiar’ with a possible erotic connection between Achilles and Helen.
(4) According to the most likely interpretation of the following iconographic representations on two vases, Achilles and Helen ‘lived’ together in the Isles of the Blessed.
