Galen’s Controversial Studies
Greco-Roman Physician Galen has been mentioned by Science Sensei in the past in both positive and negative ways. While it is true that Galen did discover a lot of useful things that are still true in medical science today, some of it was later disproven. It is likely down to the fact that Galen never once dissected a human being. Instead, he only dissected animals.
Therefore, when it came to the human heart or other organs, it was clear he did not know how they worked. That was likely due to the fact that getting a body to open up and dissect during his time was not as easy as one would want. It was also looked down upon. In some places, it was even illegal to open one up after a person’s death.
