weighing anchor

a marvellous poem by Seamus Heaney in the New Yorker ends up at:

As I age and blank on names,
As my uncertainty on stairs
Is more and more the light-headedness

Of a cabin boy’s first time on the rigging,
As the memorable bottoms out
Into the irretrievable,

It’s not that I can’t imagine still
That slight untoward rupture and world-tilt
As a wind freshened and the anchor weighed.

Exactly so. Old, trapped and grounded, sans teeth, sans eyes, sans everything; a last synapse flares, a spark in the punk; we can still set sail out of the dim caverns of the skull; somewhere there may yet be found
"still green water and clean bottom sand,
..
Above a seafloor where striped fish pass in shoals"
