Quanta pars enim novissimi signi depressione coacta versatione subiacens sub terram occultatur, tantundem eius contraria e conversationis necessitate suppressa rotatione circumacta trans locis patentibus ex obscuris egreditur ad lucem; namque vis una et necessitas utrimque simul orientem et occidentem perficit.
For whatever part of the last sign driven by its revolution passes under the earth and is concealed by its depression, to that extent the contrary sign forced upwards by the necessity of the revolution is carried round in rotation and from darkness comes to light in the visible heavens. For a single power and compulsion controls simultaneously on both sides the rising and the setting.
