Although I cannot find the original text, I expect the word "move" is not a precise translation because he goes on to say: > Animals, which move, have limbs and muscles; the earth has no limbs or muscles, therefore it does not move. It is angels who make Saturn, Jupiter, the sun, etc., turn round. If the earth revolves, it must also have an angel in the centre to set it in motion; but only devils live there; it would therefore be a devil who would impart motion to the earth.... > The planets, the sun, the fixed stars, all belong to one species - namely, that of stars. It seems, therefore, to be a grievous wrong to place the earth, which is a sink of impurity, among these heavenly bodies, which are pure and divine things.'' A sink of impurity. There's a data point that has lasted through the ages.
