In Canto Two of his poem John Shade (the poet in VN's novel Pale Fire, 1962) quotes a line from Pope's Essay on Man in which the blind beggar is mentioned:
I went upstairs and read a galley proof,
And heard the wind roll marbles on the roof.
"See the blind beggar dance, the cripple sing"
Has unmistakably the vulgar ring
Of its preposterous age. Then came your call,
My tender mockingbird, up from the hall.
I was in time to overhear brief fame
