Ea autem signa cum sint numero xii partesque duodecumas singula possideant mundi versenturque ab oriente ad occidentem continenter, tunc per ea signa contrario cursu luna, stella Mercuri, Veneris, ipse sol itemque Martis et Iovis et Saturni ut per graduum ascensionem percurrentes alius alia circuitionis magnitudine ab occidenti ad orientem in mundo pervagantur.
Now while these twelve signs possess each the twelfth part of the firmament, and continually turn from east to west, through these same signs in the opposite direction the stars of the moon, Mercury, Venus, the Sun himself and also Mars, Jupiter and Saturn as though they revolved upon a rising staircase of degrees, each with an orbit of its own, wander in the firmament from west to east.
