Lawrence Durrell's "Echo"

Below is one of my favorite Durrell poems, the fragile and gorgeous "Echo," which opens the 1956 edition of Durrell's Selected Poems. Read the poem out loud and notice its use of echo (rhyme), which builds to a crescendo in the final line, especially in the exquisite "unbeckonable," which overtly echoes "echo" in the very spine of the word, and in the final "bird," which nicely re-sounds the "b" from the prior word at the same time that it picks up the "word-heard" rhyme from lines 3 and 4, respectively. The poem manages to echo the ultimately inaudible ground from which language arises and to which it beautifully strains to return.

ECHO

Nothing is lost, sweet self,

Nothing is ever lost.
The unspoken word
Is not exhausted but can be heard.
Music that stains
The silence remains
O echo is everywhere, the unbeckonable bird!
