At the end of Canto Three of his poem John Shade (the poet in VN’s novel Pale Fire, 1962) mentions ornaments of accidents and possibilities and tells his wife Sybil that he can grope his way to some faint hope:
It did not matter who they were. No sound,
No furtive light came from their involute
Abode, but there they were, aloof and mute,
Playing a game of worlds, promoting pawns
