Zohar
A thirteenth century, Spanish compilation of Jewish mystic writings. The Zohar anticipates Copernicus’ heliocentric view of the Solar System, which says that the Earth revolves around the Sun. The Zohar states, the whole Earth spins in a circle like a ball; the one part is up when the other part is down; the one part is light when the other is dark; it is day in the one part and night in the other.
