If I Only had a Brain
Here are two striking works from two of the most noted treaties during the 16th century. These demonstrate more comparisons showing how closely animal and man where used to explain the anatomy and how in the same manner they were depicted.
Again, the importance of each work is how detailed they have become in order for others to accurately understand the part of the anatomy displayed (1). In a little different fashion, Vesalius went a more standard portrayal of the brain, versus his usual clear stylized figure.
