" That
was the last line of the Divine Comedy (and I should have written "l'amor
che move il sole e l'altre stelle") Not to pretend to learning I

a poem", was JF's answer to Dmitri on "Dar" and "Father's
butterflies".
By coincidence I had also just quoted
Dante to Dmitri: ``S'io credesse che mia risposta fosse a persona che mai
tornasse al mondo, questa fiamma staria sanza pił scosse..." and I must
also confess that I'm not learned in dantesque hells and got
it (on purpose) from T.S.Eliot's epigraph to The Love Song of Alfred J.
Prufrock.
