Galen, in the context of ancient Greek medicine, refers to Galen of Pergamon (129-~216 AD), a prominent physician, philosopher, and writer whose extensive works have had a significant influence on medical practices for centuries.
Galen's medical theories and practices formed the basis of Western medicine for over a millennium. He believed in the theory of the four humors, which posits that the body consists of four essential fluids—blood, phlegm, yellow bile, and black bile—and an imbalance of these humors leads to illness. His medical approach focused on balancing these humors through diet, exercise, and administering specific remedies. Galen also made important contributions to anatomy through dissecting animals, though his understanding of human anatomy was limited by the restrictions of his time.
Galen's writings spanned various subjects, including biology, physiology, pathology, pharmacology, and even philosophy. He produced a vast body of work estimated to be around 500 treatises, many of which were preserved and translated into Latin during the Middle Ages. These translations aided in the transmission of his medical knowledge throughout medieval Europe.
While some of Galen's theories and treatments have been proven inaccurate over time, his lasting impact is indisputable. His theories shaped medical education and practice for centuries, and many of his teachings were followed until the advent of modern medicine. Galen's name has become synonymous with classical Greek medicine and is often used to refer to ancient medical practices and ideas.
