Spinning through Ada (chapter 3,III), I only checked the word carousel ( with one "s), here a the rotating book-stand :
Van’s eye over his umbrella crook traveled around a carousel of Sapsucker paperbacks ...
And yet, Van will then describe Lucette as in a picture, drawn by Toulouse Lautrec ( Cf. B.Boyd's Ada annotations & book-cover), sitting inside a "cabaret" ( not named as such) ..."that sort of bawdy, albeit smart, place which decent women did not frequent ...as he was in the act of wiping the lenses of his black-framed spectacles, made out, through the optical mist (Space’s recent revenge!), the girl whose silhouette he recalled having seen now and then...like Blok’s Incognita. It was a queer feeling — as of something replayed by mistake, part of a sentence misplaced on the proof sheet, a scene run prematurely, a repeated blemish, a wrong turn of time."
PALE FIRE
Other "rotating" images (page 47,line 413-14): A nymph came pirouetting, under white/Rotating petals, in a vernal rite/...
Commentary: 1.(page 93,lines 47-48): the poplar-curtained Roman-tiered football field.[ this image will reappear in Bend Sinister, circus and stage].. youngster flying - on a long control line in a droning circle - a motor-powered model plane.
2.( page 261, line 810): The Daedalian plan simplified by a look from above - smeared out as it were by the splotch of some master thumb that made the whole involuted, boggling thing one beautiful straight line."(eve of death: Franklin Lane)
The "fan" (object,verb and various meanings) comes close to peacock, iridule, alder/decoy, nacreous, blurred vision, kaleidoscope, glasses, fisherman and even in relation to death in order to convey something "ghostly" that has " no effect whatever on his real moves, on the real play." ( a disputable abstract, indeed, but those who'll take the trouble to accompany the slow building up of Prospero-like images might come to agree with me...)
Bend Sinister:
1..I must
put on my spectacles,' said Krug...He held them before
his face and looked through them at a distant window. The left glass showed
a dim spiral nebula in the middle not unlike the imprint of a ghostly
thumb... 3.
