Describing the young Prince's chaste romance with Fleur de Fyler, Kinbote (in VN's novel Pale Fire, 1962, Shade’s mad commentator who imagines that he is Charles the Beloved, the last self-exiled king of Zembla) mentions his - or rather, his grandfather's - cheval glass, a triptych of bottomless light, a really fantastic mirror, signed with a diamond by its maker, Sudarg of Bokay:
Her presence at night did not kill insomnia, but at least kept at bay the strong ghost of Queen Blenda. Between exhaustion and drowsiness, he trifled with paltry fancies, such as getting up and pouring out a little cold water from a decanter onto Fleur's naked shoulder so as to extinguish upon it the weak gleam of a moonbeam. Stentoriously the Countess snored in her lair. And beyond the vestibule of his vigil (here he began falling asleep), in the dark cold gallery, lying all over the painted marble and piled three or four deep against the locked door, some dozing, some whimpering, were his new boy pages, a whole mountain of gift boys from Troth, and Tuscany, and Albanoland.
He awoke to find her standing with a comb in her hand before his - or rather, his grandfather's - cheval glass, a triptych of bottomless light, a really fantastic mirror, signed with a diamond by its maker, Sudarg of Bokay. She turned about before it: a secret device of reflection gathered an infinite number of nudes in its depths, garlands of girls in graceful and sorrowful groups, diminishing in the limpid distance, or breaking into individual nymphs, some of whom, she murmured, must resemble her ancestors when they were young – little peasant garlien combing their hair in shallow water as far as the eye could reach, and then the wistful mermaid from an old tale, and then nothing.
On the third night a great stomping and ringing of arms came from the inner stairs, and there burst in the Prime Councilor, three Representatives of the People, and the chief of a new bodyguard. Amusingly, it was the Representatives of the People whom the idea of having for queen the granddaughter of a fiddler infuriated the most. That was the end of Charles Xavier's chaste romance with Fleur, who was pretty yet not repellent (as some cats are less repugnant than others to the good-natured dog told to endure the bitter effluvium of an alien genus). With their white suitcases and obsolete musical instruments the two ladies wandered back to the annex of the Palace. There followed a sweet twang of relief - and then the door of the anteroom slid open with a merry crash and the whole heap of putti tumbled in. (note to Line 80)
A mirror-maker of genius, Sudarg of Bokay is Jakob Gradus (Shade's murderer) in reverse. In R. L. Stevenson's Strange Case of Dr Jekyll and Mr Hyde (1886) there is a cheval-glass in Dr. Jekyll's cabinet:
It was late in the afternoon, when Mr. Utterson found his way to Dr. Jekyll's door, where he was at once admitted by Poole, and carried down by the kitchen offices and across a yard which had once been a garden, to the building which was indifferently known as the laboratory or dissecting rooms. The doctor had bought the house from the heirs of a celebrated surgeon; and his own tastes being rather chemical than anatomical, had changed the destination of the block at the bottom of the garden. It was the first time that the lawyer had been received in that part of his friend's quarters; and he eyed the dingy, windowless structure with curiosity, and gazed round with a distasteful sense of strangeness as he crossed the theatre, once crowded with eager students and now lying gaunt and silent, the tables laden with chemical apparatus, the floor strewn with crates and littered with packing straw, and the light falling dimly through the foggy cupola. At the further end, a flight of stairs mounted to a door covered with red baize; and through this, Mr. Utterson was at last received into the doctor's cabinet. It was a large room fitted round with glass presses, furnished, among other things, with a cheval-glass and a business table, and looking out upon the court by three dusty windows barred with iron. The fire burned in the grate; a lamp was set lighted on the chimney shelf, for even in the houses the fog began to lie thickly; and there, close up to the warmth, sat Dr. Jekyll, looking deathly sick. He did not rise to meet his visitor, but held out a cold hand and bade him welcome in a changed voice. ("Incident of the Letter")
"The Face in the Cheval-Glass" is a phrase that refers to a specific, uncanny moment of self-reflection often associated with Robert Louis Stevenson's work, particularly his story Strange Case of Dr Jekyll and Mr Hyde. The Face in the Target is the first story in the short story collection The Man Who Knew Too Much (1922) by G. K. Chesterton. In Orthodoxy (1908) G. K. Chesterton says that a man who commits suicide defiles every flower by refusing to live for its sake:
I put these things not in their mature logical sequence, but as they came: and this view was cleared and sharpened by an accident of the time. Under the lengthening shadow of Ibsen, an argument arose whether it was not a very nice thing to murder one's self. Grave moderns told us that we must not even say "poor fellow," of a man who had blown his brains out, since he was an enviable person, and had only blown them out because of their exceptional excellence. Mr. William Archer even suggested that in the golden age there would be penny-in-the-slot machines, by which a man could kill himself for a penny. In all this I found myself utterly hostile to many who called themselves liberal and humane. Not only is suicide a sin, it is the sin. It is the ultimate and absolute evil, the refusal to take an interest in existence; the refusal to take the oath of loyalty to life. The man who kills a man, kills a man. The man who kills himself, kills all men; as far as he is concerned he wipes out the world. His act is worse (symbolically considered) than any rape or dynamite outrage. For it destroys all buildings: it insults all women. The thief is satisfied with diamonds; but the suicide is not: that is his crime. He cannot be bribed, even by the blazing stones of the Celestial City. The thief compliments the things he steals, if not the owner of them. But the suicide insults everything on earth by not stealing it. He defiles every flower by refusing to live for its sake. There is not a tiny creature in the cosmos at whom his death is not a sneer. When a man hangs himself on a tree, the leaves might fall off in anger and the birds fly away in fury: for each has received a personal affront. Of course there may be pathetic emotional excuses for the act. There often are for rape, and there almost always are for dynamite. But if it comes to clear ideas and the intelligent meaning of things, then there is much more rational and philosophic truth in the burial at the cross-roads and the stake driven through the body, than in Mr. Archer's suicidal automatic machines. There is a meaning in burying the suicide apart. The man's crime is different from other crimes -- for it makes even crimes impossible. (Chapter 5. The Flag of the World)
According to Kinbote (the author of a remarkable book on surnames), the name Fleur de Fyler means "Defiler of Flowers:"
No such qualms disturbed him as he sat now on the terrace of her villa and recounted his lucky escape from the Palace. She enjoyed his description of the underground link with the theater and tried to visualize the jolly scramble across the mountains; but the part concerning Garh displeased her as if, paradoxically, she would have preferred him to have gone through a bit of wholesome hough-magandy with the wench. She told him sharply to skip such interludes, and he made her a droll little bow. But when he began to discuss the political situation (two Soviet generals had just been attached to the Extremist government as Foreign Advisers), a familiar vacant express on appeared in her eyes. Now that he was safely out of the country, the entire blue bulk of Zembla, from Embla Point to Emblem Bay, could sink in the sea for all she cared. That he had lost weight was of more concern to her than that he had lost a kingdom. Perfunctorily she inquired about the crown jewels; he revealed to her their unusual hiding place, and she melted in girlish mirth as she had not done for years and years. "I do have some business matters to discuss," he said. "And there are papers you have to sign." Up in the trellis a telephone climbed with the roses. One of her former ladies in waiting, the languid and elegant Fleur de Fyler (now fortyish and faded), still wearing pearls in her raven hair and the traditional white mantilla, brought certain documents from Disa's boudoir. Upon hearing the King's mellow voice behind the laurels, Fleur recognized it before she could be misled by his excellent disguise. Two footmen, handsome young strangers of a marked Latin type, appeared with the tea and caught Fleur in mid-curtsey. A sudden breeze groped among the glycines. Defiler of flowers. He asked Fleur as she turned to go with the Disa orchids if she still played the viola. She shook her head several times not wishing to speak without addressing him and not daring to do so while the servants might be within earshot. (note to Lines 433-434)
