Although by tradition and Vesalius's own comments this work has been considered to be the first of many plagiarisms of Vesalius's Fabrica and Epitome, Geminus gave full credit to Vesalius in a bold headline on the first leaf of text. He did, however, redraw Vesalius's woodcuts without permission. This is the second work printed in England with engraved plates. The new medium of copperplate engraving used by Geminus allowed a sharpness of line impossible for the wood engravers employed by Vesalius. The title page was called by Hind "the first engraving of any artistic importance produced in England'. The book provided a summary of Vesalius's discoveries more complete than the Epitome but without the size and expense of the Fabricia.
