I associated it (the word 'Hourloupe', as title of his longest series of work he made exclusively from 1962 to 1974, fh) by assonance with 'hurler' (to shout), hululer (to howl), loup, (wolf), 'Riquet à la Houppe' and the title of Maupassant's book 'Le Horla', inspired by mental distraction.
God is a novelist. He uses all sorts of literary devices: alliteration, assonance, rhyme, synecdoche, onomatopoeia. But of all of these, His favorite is foreshadowing.And that is what God was doing at the Cloisters and with Eudora Welty. He was foreshadowing. He was laying traps, leaving clues, clues I could have seen had I been perceptive enough.
