And old King Priam was first to see him coming,
surging over the plain, blazing like the star
that rears at harvest, flaming up in its brilliance –
far outshining the countless stars in the night sky,
that star they call Orlon’s Dog – brightest of all
but a fatal sign emblazoned on the heavens,
it brings such killing fever down on wretched men.
So the bronze flared on his chest as on he raced.

– Homer

The Iliad, Book 22, lines 31-38. King Priam watches as Achilles runs towards Troy, his bronze armor shining like the brightest star in the night sky, according to one of Homer’s beautiful epic similes.
