It's never too late for an Easter poem. I found this, the first Walcott poem I have read, at Mead's site.
Easter
(From Collected Poems 1948-1984.)
Anna, my daughter,
you have a black dog
that noses your heel,
selfless as a shadow;
here is a fable
about a black dog:
On the last sunrise
the shadow dressed with Him,
it stretched itself also—
they were two big men
with one job to do.
But life had been lent to one
only for this life.
They strode in silence toward
uncontradicting night.
The rats at the Last Supper
shared crumbs with their shadows,
the shadow of the bread
was shared by the bread;
when the candles lowered,
the shadow felt larger,
so He ordered it to leave;
He said where He was going
it would not be needed,
for there there’d be either
radiance or nothing.
It stopped when He turned
and ordered it home,
then it resumed the scent;
it felt itself stretching
as the sun grew small
like the eyes of the soldiers
receding into holes
under the petrified
serpents on their helmets;
the narrowing pupils
glinted like nailheads,
so before He lay back
it crept between the wood
as if it were the pallet
they had always shared;
it crept between the wood
and the flesh nailed to the wood
and it rose like a black flag
as the crossbeam hoisted
itself and the eyes
closed very slowly
extinguishing the shadow—
everything was nothing.
Then the shadow slunk away,
crawling low on its belly,
and it left there knowing
that never again
would He ever need it;
it reentered the earth,
it didn’t eat for three days,
it didn’t go out,
then it peeped out carefully
like a mole from its hole,
like a wolf after winter,
like a surreptitious serpent,
looking for those forms
that could give back its shape;
then it ran out when the bells
began making wide rings
and rings of radiance;
it keeps nosing for His shape
and it finds it again, in
the white echo of a pigeon
with its wings extended
like a shirt on a clothesline,
like a white shirt on Monday
dripping from a clothesline,
like the greeting of a scarecrow
or a man yawning
at the end of a field.
