Questio de aqua et terra (23)

(23) Consequentia declaratur sic: Sit celum circumferentia in qua tres cruces, aqua in qua due, terra in qua una; et sit centrum celi et terre punctus in quo A, centrum vero aque ecentrice punctus in quo B; ut patet in figura signata. Dico ergo quod, si aqua erit in A et habeat transitum, quod naturaliter movebitur ad B, cum omne grave moveatur ad centrum proprie circumferentie naturaliter; et cum moveri ab A ad B sit moveri sursum, cum A sit simpliciter deorsum ad omnia, aqua movebitur naturaliter sursum; quod erat primum impossibile, quod sequi dicebatur. (23) The sequence is thus established. Let the circumference marked with three crosses be heaven, that marked with two crosses water, and that marked with one, earth. And let the centre of heaven and earth be the point marked A, and the centre of water, which is excentric, the point marked B, as shown in the marked figure. I say, then, that if there should be water at A having a free course, it would naturally move to B, since everything that has weight naturally moves to the centre of its proper circumference; and since moving from A to B is moving up (since A is absolutely down, with reference to everything), water will naturally move up, which was the first impossibility mentioned above.
