if you are tired and it’s dark without any lights and you are walking down a road, the objects in the road seem to take on a strange shape. Your mind see trees as giants and you see strange things looming out of the dark. So it must have seen to the warriors in the Iliad fighting on the plain of Troy. Tney did not fight in the dark but mist and the dust of war must have made it seem like night and the warriors would have been tired. So looking at the oak tree near Troy it would have been easy to imagine a god leaning against it.
Then the sons of the Achaians would have taken high-gated Troy, had not Phoebus Apollo roused up glorious Agenor, the strong and blameless son of Antenor. He put courage in his heart. He came and stood beside him to keep the strong hands of death from him, leaning on the oak tree and he was covered by a thick mist.
ἔνθά κεν ὑψίπυλον Τροίην ἕλον υἷες Ἀχαιῶν,
εἰ μὴ Ἀπόλλων Φοῖβος Ἀγήνορα δῖον ἀνῆκε
φῶτ᾽ Ἀντήνορος υἱὸν ἀμύμονά τε κρατερόν τε.
ἐν μέν οἱ κραδίῃ θάρσος βάλε, πὰρ δέ οἱ αὐτὸς
ἔστη, ὅπως θανάτοιο βαρείας χεῖρας ἀλάλκοι
φηγῷ κεκλιμένος: κεκάλυπτο δ᾽ ἄρ᾽ ἠέρι πολλῇ.
