A Reading of "The Last One"
Format: Paperback
This poem represents Merwin at his insidious best, the conversational tone of the poem slowly leading to something imminently and undefinably dark, doom-laden. The poem was originally published in "The Lice" a book of poems written in the French countryside where, Merwin says, "I felt at once a profound attraction to the rural world in which I was living and a disquieting recognition of the fragility and uncertainty of my relation to it."
"The Last One" ominously conveys that disquiet.

I have many books by Mr Merwin and I like the Budhist mindset that shines through.
