Summary Of Galen's Book 'On Anatomical Procedures'

The person to read Galen’s book On Anatomical Procedures, a book about his surgical findings, was Andreas Vesalius. Upon reading this book, Vesalius decided to do his own dissections to see just how true Galen’s observations had been. He had been granted a job as a surgeon in 1573 right after medical school at just 23 years old. As Galen had only used animals as his source of dissection, Vesalius found that Galen was wrong about anatomy in many occasions. One of these incidences occurred because Galen said the great blood vessels come from the liver. Vesalius found this was not true during his own dissections, because the great blood vessels really originated at the heart. He was able to show that the lower jaw was in one piece, not two.
Chemistry was more than 100 years behind astronomy and anatomy. One chemist, Robert Boyle, found that the volume of a gas varies with the pressure exerted on it. He was also the one who discovered “little particles of all shapes and sizes”. Boyle said that these particles were the basic building blocks of everything. They come in all shapes and sizes. These particles would later be called atoms and put into the table of elements by Antoine Lavoisier. Lavoisier was able to show that chemicals combined to make things, such as oxygen and hydrogen forming water. This was the beginning of modern
The people of this time were brilliant and made huge advances in astronomy, anatomy, and chemistry once people began finding secular reasons for why things happen other than allowing the Catholic Church to tell them what to believe. While many of the well-known discoverers of the time were men, there were also many women that got involved. All of the discoveries led to us knowing what is currently known as facts that were once just debated theories. Without the influence from these spectacular individuals, modern medicine, chemistry, astronomy or even women’s rights may have never been what they are
