When Half the Poem is by a different Poet

I don't know if I am just slow, lazy, or moody about when I read the book, but I am still working on Carlos Pintado's Nine Coins/Nueve monedas.  Amongst those read today included "Portico":

I know that in my life's last moment,

that line of Walt Whitman's will come to me:

And whoever walks a furlong without sympathy

walks to his own funeral . . . 

Considering how many entries I have made regarding Whitman, it only seemed sensible to share this as well.
