In poetry:

Shall we, when the grim shape
Roars upward, dance and sing?
Yes: if we honour rape,
If we take pride to Ring
So bountifully on space
The sperm of our long woes, our large disgrace.

Who swims enwombed?
Who lies with the waters of his silent passion, womb-

Bound away in the ‘Waterwitch’ to the west’ard we’ll go.

there they blow, there they blow, hot wild white breath out of
the sea!
