Dryander was among the first to make illustrations after his own dissections. His unfinished guide to dissection entitled Anatomiae, expanded from the Anatomia published the previous year, is one of the most important of the pre-Vesalian anatomies. Choulant ascribes the woodcuts to the school of Hans Brosamer (Frankfurt) while Herrlinger suggests that they may come from the Basel school. This book includes the first printing of two other short works on dissection: Gabriele Zerbi's Anatomia infantis and Copho’s Anatomia porci.
