Seamus Heaney - Lovers on Aran

The timeless waves, bright, sifting, broken glass,
Came dazzling around, into the rocks,
Came glinting, sifting from the Americas

To posess Aran. Or did Aran rush
to throw wide arms of rock around a tide
That yielded with an ebb, with a soft crash?

Did sea define the land or land the sea?
Each drew new meaning from the waves' collision.
Sea broke on land to full identity.

Seamus Heaney
