The Confessions of Nat Turner as told to Thomas R. Gray (1831)
"Was not Christ crucified. And by signs in the heavens that it would make known to me when I should commence the great work—and until the sign appeared, I should conceal it from the knowledge of men—And in the appearance of the sign, (the eclipse of the sun last February) I should arise and prepare myself, and slay my enemies with their own weapons."
