Odysseus by W.S.Merwin
Always the setting forth was the same,
Same sea, same dangers waiting for him
As though he had got nowhere but older.
Behind him on the receding shore
The identical reproaches, and somewhere
Out before him, the unraveling patience
He was wedded to. There were the islands
Each with its woman and twining welcome
To be navigated, and one to call "home".
The knowledge of all that he betrayed
Grew till it was the same whether he stayed
Or went. Therefore he went. And what wonder
If sometimes he could not remember
Which was the one who wished on his departure
Perils that he could never sail through,
And which, improbable, remote, and true,
Was the one he kept sailing home to ?
Because I love a poem that can do all its telling in 17 lines.
