From the poem
. . . But this is waking,
and this his favorite horse, whom he's never named,
that's how much he loves her, though she's
branded, sure, the way all his horses are: "Without
mystery, what chance for hope"–in Latin, on the left
flank where it catches the light, loses it, the king
sashless and in flight, though it looks processional,
he thinks–stately, almost–as the newly fallen believe
at first there's still a plan available: they'll save themselves.
