Marie is Seamus Heaney’s wife. This is his poem:
Love, I shall perfect for you the child
Who diligently potters in my brain
Digging with heavy spade till sods were piled
Or puddling through muck in a deep drain.
Yearly I would sow my yard-long garden.
I’d strip a layer of sods to build the wall
That was to exclude sow and pecking hen.
Yearly, admitting these, the sods would fall.
Or in the sucking clabber I would splash
Delightedly and dam the flowing drain,
But always my bastions of clay and mush
Would burst before the rising autumn rain.
Love, you shall perfect for me this child
Whose small imperfect limits would keep breaking:
Within new limits now, arrange the world
And square the circle: four walls and a ring.
