Andries van Wezel (31 December 1514 – 15 October 1564), latinised as Andreas Vesalius (/ v ɪ ˈ s eɪ l i ə s /), [2] [a] was an anatomist and physician who wrote De Humani Corporis Fabrica Libri Septem (On the fabric of the human body in seven books), which is considered one of the most influential books on human anatomy and a major advance over the long-dominant work of Galen.
Galen's writings were shown by Vesalius to describe details present in monkeys but not in humans, and he demonstrated Galen's limitations through books and hands-on demonstrations despite fierce opposition from orthodox pro-Galenists such as Jacobus Sylvius. Since Galen states that he is using observations of monkeys (human dissection was ...
The Fabrica is known for its highly detailed illustrations of human dissections, often in allegorical poses.. De Humani Corporis Fabrica Libri Septem (Latin, "On the Factory of the Human Body in Seven Books") is a set of books on human anatomy written by Andreas Vesalius (1514–1564) and published in 1543.
[53] In 1540, Vesalius gave a public demonstration of the inaccuracies of Galen's anatomical theories, which are still the orthodoxy of the medical profession. Vesalius now has on display, for comparison purposes, the skeletons of a human being alongside that of an ape of which he was able to show, that in many cases, Galen's observations were ...
Vesalius picked up from the work of Galen (129–c. 200 CE) which was based on the dissection of animals from pigs to apes. [12] The works of Galen would be accepted until Vesalius. He would challenge the medieval views of human anatomy made by Galen that had been taught for centuries. Vesalius paved he foundation of modern anatomy and most of ...
The irony is that Galen himself had emphasized the fact that one should make one's own observations instead of using those of another, but this advice was lost during the numerous translations of his work. As Vesalius began to uncover these mistakes, other physicians of the time began to trust their own observations more than those of Galen. An ...
Galen wrote that the bone of the arm is the longest bone in the human body, but Vesalius found that the bone of the thigh is actually the longest bone in human body. At age 25 Vesalius realized that the anatomical knowledge of Galen was derived from animal anatomy and therefore Galen had never dissected a human body.
Vesalius dissected human corpses, whereas Galen dissected animal corpses. Published in 1543, Vesalius' De humani corporis fabrica [ 89 ] was a groundbreaking work of human anatomy . It emphasized the priority of dissection and what has come to be called the "anatomical" view of the body, seeing human internal functioning as an essentially ...
