Still another example of how human and animal anatomy where so closely linked during the 15th century can be show in a treatise by Pierre Belon (1517 - 64), L’Histoire de la nature des osyeaux (History of the Nature of Birds). Vastly used in the zoology field, we still find that one of his images directly puts the bones of a human being in direct comparison to that of a bird's skeleton.
What I found to be truly interesting about this treatise is the manner in which the bones of the bird are posed. The bird is arranged very unnaturally, rendered as how a human being would stand, rather than how an actual bird is. Belon has the drawings labeled to identify the different areas on the skeleton to reflect both human and bird. If it was not for knowing that this was a scaled image used to be able to easily compare, one can even believe that the bird is intended to be a monster.
The skeleton standing alone is also from Vesalius and it just shows how much detail each took in the drawing of the skeleton. While Vesalius follows in his distinct style of staging the bones as if was posing for this drawing, Belon goes the direct scientific staging in order best identify all its parts.
