And death shall have no dominion.
Dead men naked they shall be one
With the man in the wind and the west moon;
When their bones are picked clean and the clean bones gone,
They shall have stars at elbow and foot;
Though they go mad they shall be sane,
Though they sink through the sea they shall rise again;
Though lovers be lost love shall not;
And death shall have no dominion.
This line and the two succeeding it are paradoxes that are used to describe how people are remembered in retrospect. The three lines use the idea of mythology and the constellations as a lens through which to understand these apparent paradoxes. 
 This first line may be a reference to Hercules, who  went mad and killed his wife and children . This is the event that caused him to undertake the twelve labours as atonement, which is why we know him today. Hercules is not remembered as a mad man, but a hero, because he lived the rest of his life that way.
