This unique edition of Oswald Schreckenfuchs' massive commentary contained, for the first time in the Theoricae novae<\/i> printed tradition, a series of three-dimensional diagrams intended to complement the ordinary diagrams of the orbs, circles, axes and poles of the planets and the eighth sphere. These diagrams are printed on one side of two bifolia<\/i>. In some copies the bifolia<\/i> form one gathering b (four folios), bound after the preface; in others the figures have been cut, and each is inserted in the appropriate place in the treatise. They are not lettered and have no legend, though some of their elements are labelled, as they must be used in association with the diagrams in the text. This figure represents the movement of the eighth sphere.<\/p>" }, { "label": "Date of Creation", "value": "1556" }, { "label": "Title", "value": "The eighth sphere" }, { "label": "Material", "value": "paper" }, { "label": "Classmark", "value": "Wren S.5.20" }, { "label": "Note(s)", "value": "
