Johann Dryander, Anatomiae, hoc est, Corporis humani dissectionis pars prior, Marburg: E. Cervicornum, 1537, e ij recto, woodcut, leaf height 19.3 cm, 5000.d.70.

Johannes Dryander (1500-1560) studied mathematics and medicine at the University of Paris, attending several dissections there. He became professor of mathematics and medicine at Marburg University, and in 1536 published, for the edification of his students, his anatomy of the human head. This is the second, enlarged edition including additional illustrations of the anatomy of the thorax and the heart. It is entitled the First part of the anatomy, that is, of the dissection of the human body, as he intended to cover the rest of the human body in the second part, which was, however, never published.

In this figure, A shows the dura mater, B the pia mater with branches of veins, C the left part of the brain, D the right part of the brain, and E the boundary between the two. Dryander explains in the accompanying text that the dura mater divides the left and the right brains (falx cerebri), as it does the front and the back of the brain.
