(Chapter 15) Footnote 33:

Though the order of composition of Galen’s vast oeuvre is unknown, references in De anat. adm. to earlier works, including De usu partium and De ossibus, signaled to Vesalius that it was the latest Galenic work well known to him. Of the importance of Galen’s treatise on dissection to Vesalius, Singer writes “this book by Galen has a special place in the modern revival of anatomy, since it was study of the Latin translation of it, published by Guenther of Andernach is 1531, that started Vesalius on his triumphant career.” (1956, p. xiii).
