The goddess Thetis proceeds to bring for Achilles the armor that was made for him by the god Hephaistos, I.19.003, and she finds the hero embracing the body of Patroklos and weeping over it, mourning together with all his fellow warriors, the Myrmidons, I.19.004–006; she now makes a formal presentation of the armor to Achilles, I.19.007–013. At the sight of this armor, all the Myrmidons recoil: no one can bear to look at the divine work of art, I.19.014–015—no one, that is, except for Achilles, who now looks directly at the Shield, I.19.015–017, and whose eyes, as he is looking, now give off a terrifying selas ‘flash of light’, I.19.017. The first time we saw this word selas in the Iliad was at I.08.076, where it referred to the lightning that comes from Zeus as he thunders from on high on the top of Mount Ida—and this flash of light brings holy terror for the Achaeans, I.08.076–077. See the comment on I.08.066–077. There is a comparable reference at I.17.739 to the selas ‘flash of light’ in a thunderstorm. See the comment on I.17.736–741. Other evocative occurrences of selas ‘flash of light’ include the references at I.08.509 and at I.08.563 to the threatening fires of the Trojans. And we see yet again this powerful word in the context of I.15.599–600: it is said there that Zeus has been waiting to see with his own divine eyes the selas ‘flash of light’, I.15.600, that will appear when the first of the beached Achaean ships is set on fire. Once this divine vision is visualized, the Will of Zeus will have been fulfilled. Thus this word selas ‘flash of light’ signals the driving force of the whole epic, which is the Will of Zeus. See the comment on I.15.592–602. Another powerful moment where the Will of Zeus manifests itself as a selas ‘flash of light’ happens at I.18.214, where this word refers to the fire that bursts from the head of the enraged Achilles. See the comment on I.18.214. With regard to I.15.599–600, I also note a coextensiveness between the selas ‘flash of light’ at I.15.600 and the terrifying look of Zeus. I deliberately use the word look here because, unlike other English words for the act of seeing, the verb look and the noun look or looks can refer to a stream of vision not only as it comes into the eye but also as it goes out of it. Zeus can look at the terrifying flash of light when the beached ship of Protesilaos is set on fire, but that look of his can translate into the terrifying flash of light that comes out of his own eye in the act of his casting his thunderbolt. Zeus hurls his thunderbolt by casting his eye on the target: see the comment on I.13.242–244. I see a comparable pattern of coextensiveness here at I.19.015–017: the selas ‘flash of light’ at I.19.017 that comes from the terrifying look of Achilles as he looks at the Shield will translate into a flash of light that comes from the Shield itself: only Achilles dares to look at it, while the other Myrmidons shrink back in terror, avoiding the gaze.
