Compendiosa totius anatomie delineatio by Belgian engraver, mathematical and surgical instrument maker, Thomas Geminus (Thomas Lambert or Lambrit) was a slightly abridged version of Vesalius's Epitome illustrated with figures from both the Fabrica and the Epitome re-engraved in copperplate by Geminus. Geminus's work introduced Vesalian anatomy to England, filling an important need by providing a summary view of Vesalius's anatomical discoveries more complete than the Epitome, less bulky and expensive than the Fabrica, and illustrated— via the new medium of copperplate engraving— with a clarity of line impossible even for the highly skilled wood engravers employed by Vesalius. The work was dedicated to Henry VIII, who in 1540 had given assent to an Act uniting Barbers and Surgeons into one Company. In the same year another Act authorized the supply of the cadavers of four executed criminals to the Barber and Surgeons Company for dissection. Geminus undoubtedly intended his book to supply needed information to English surgeons in the spirit of the new legislation. However, Vesalius did not authorize publication of the Compendiosa, and he complained about it bitterly in his China-Root Epistle (1546), so that even though Geminus declared Vesalius's authorship in the headline on leaf A1, the Compendiosa has always been considered the first of the many plagiarisms of Vesalius's anatomical works.
