This is the second edition of Apianus’s Instrumentum primi mobilis, first published in 1534. Although reduced in format, the text is essentially identical to the first portion of the first edition. However, Apianus has provided a new preface and has elected not to include the astronomy text of Gerardus Cremonensis issued with the first edition. Another noteworthy difference is the addition of two new leaves of text (c4-d1) describing a different form of quadrant (shown on the title page and again on leaf d1 together with supporting diagrams).
