The black slave preacher Nat Turner witnessed an annular eclipse of the Sun on February 12th 1831.
It was seen as a vision from God of a “black angel” overtaking a “white angel”. Turner saw another astronomical spectacle a naked eye sunspot on August 12th 1831. This all fuelled the possibility of a black slave rebellion.
The rebellion itself began on August 21st 1831 but was quickly crushed and Turner was hanged on November 11th 1831.
