A summary recapitulation and description of the figures of the world; also the refutation of the sphere.

It is written: In the beginning God made the heaven and the earth. We therefore first depict along with the earth, the heaven which is vaulted and which has its extremities bound together with the extremities of the earth. To the best of our ability we have endeavoured to delineate it on its western side and its eastern; for these two sides are walls, extending from below to the vault above. There is also the firmament which, in the middle, is bound together with the first heaven, and which, on its upper side, has the waters according to divine scripture itself. The position and figure are such as here sketched. To the extremities on the four sides of the earth the heaven is fastened at its own four extremities, making the figure of a cube, that is to say, a quadrangular figure, while up above it curves round in the form of an oblong vault and becomes as it were a vast canopy. And in the middle the firmament is made fast to it, and thus two places are formed.

From the earth to the firmament is the first place, this world, namely, in which are the angels and men and all the present state of existence.
