Flat on this bed, that by them may be shown
That this is my south-west discovery,
Per fretum febris, by these straits to die,
I joy, that in these straits I see my west;
For, though their currents yield return to none,
What shall my west hurt me? As west and east
In all flat maps (and I am one) are one,
So death doth touch the resurrection.
Is the Pacific Sea my home? Or are
The eastern riches? Is Jerusalem?
Anyan, and Magellan, and Gibraltar,
All straits, and none but straits, are ways to them,
Whether where Japhet dwelt, or Cham, or Shem.
We think that Paradise and Calvary,
Christ's cross, and Adam's tree, stood in one place;
Look, Lord, and find both Adams met in me;
The three sons of Noah: Japheth, Ham, and Shem (Genesis 6:10), whose descendants respectively spread to Europe, Africa, and Asia. 
 
 All of these places are there for Donne to explore on his route to paradise.
