Two creatures

After Edward Arlington Robinson.  I make no claim for this to be good work; it just turned up in my head this afternoon.  (Here and here are Wikipedia links which may help.)

Two creatures' eyes have seen the sun,
and now their lids are filled with dust.
But if their eyes were blue, or brown,
I cannot tell, and yet I must.

St Claire's an Amiable Child
who sleeps secure and snug as Grant,
but who can tell me of his eyes?
(The city parks curator can't.)

And Johnson had a cat named Hodge
who fed on oysters, and was fine;
his coat was black, but not his eyes,
whose shade I cannot now divine.

Two creatures hold me in their gaze,
and thoughts of it I can't dislodge:
the nature of your eyes, my friends,
your sleeping eyes, St Claire and Hodge?
