Tabulae anatomicae, a collection of Bartolomeo Eustachi's anatomical engravings, was first published over one hundred years after Eustachi’s death. Eustachi was known for his strong defense of the Galenic tradition. His plates introduced numbered rulers on the edges of images (instead of marking the image itself with small letters and numbers) to help readers locate relevant text in the book.
