The Disappearing Island, Seamus Heaney
Once we presumed to found ourselves for good
Between its blue hills and those sandless shores
Where we spent our desperate night in prayer and vigil,
Once we had gathered driftwood, made a hearth
And hung our cauldron like a firmament,
The island broke beneath us like a wave.
The land sustaining us seemed to hold firm
Only when we embraced it in extremis.
All I believe that happened there was vision.
