Thirty-Two Years Later

[Achebe]

She pulls her eyes
out of their sockets, ...the opening is startling, and effective.
holds them tightly ...'tightly' is a nice choice of word.It suggests that the 'eyes' - a metaphor for a poem etc (see below) - are important to the person
in each hand,
and tells me,

         "See the things
         I have seen,
         the wonders.
         This is my gift
         to you."  ................................excellent. I get the impression that you're reading someone's journal  / book of poems / something artsy and autobiographical

I hold them close to me,
try to look through them. ...still good control of the metaphor

I suppose it is the law
of nature their warm sight
fades a bit to dry and hollow— ... I don't see the connection between 'warmth' and 'hollowness'. this stanza makes no sense for me.

But these eyes have seen ... not sure what the 'but' is supposed to contradict
all the fragments of everything
good and bad ever seen— ... 'everything' and 'ever' confuse me - are you being hyperbolic for the sake of it, or is there a meaning that I'm missing?

my hoary silence, the fat ...'hoary' anything is a bit overused, though not exactly a cliche
of the day, a declension ...excellent enjambment, memorable phrase
of starlings against our sky. ..it sounds wonderful, but I'm not sure about 'declension' - what does it mean, other than something in grammar?
