Carson’s Sappho composts a dozen ways and more. One one student noted is, the enjambed and lightly punctuated line breaks a (propositional) thought into smaller (experiential) thoughts.
And in it cold water makes a clear sound through
apple branches and with roses the whole place
is shadowed and down from radiant-shaking leaves
sleep comes dropping.
The poet composes the line. The line composts the sentence. That’s general to poetry but more prominent here than often it is. “And in it cold water makes a clear sound through” is a whole phase and phrase and frame of feeling. Notwithstanding its unfinish as a sentence. The effect is to reorient thought — to reorient thinking — away from proposition and toward proprioception.
