There sat down, once, a thing on Henry's heart
só heavy, if he had a hundred years
& more, & weeping, sleepless, in all them time
Henry could not make good.
Starts again always in Henry's ears
the little cough somewhere, an odour, a chime.
And there is another thing he has in mind
like a grave Sienese face a thousand years
would fail to blur the still profiled reproach of. Ghastly,
with open eyes, he attends, blind.
Berryman is referring to another event in his life that has left him so bitter and full of grief. This would be when his wife left him.
