Claggart deliberately advanced within short range of Billy, and mesmerically looking him in the eye, briefly recapitulated the accusation. Not at first did Billy take it in. When he did the rose- tan of his cheek looked struck as by white leprosy. He stood like one impaled and gagged. Meanwhile the accuser’s eyes, removing not as yet from the blue, dilated ones, underwent a phenomenal change, their wonted rich violet colour blurring into a muddy purple. Those lights of human intelligence losing human expression, gelidly protruding like the alien eyes of certain uncatalogued creatures of the deep.
—Herman Melville, Billy Budd, 1924.
