Dioscorides 5 What tradition did Galen start?

The ancient Roman physician Galen also wrote a large number of pharmacological works, and together they started the tradition of "medicinal naturalism". Although the Materia Medica has been criticized by some scholars as being merely a list, along the lines of Pliny the Elder's methodology and thinking, this kind of museum writing continued for 1500 years, during which time the material continued to increase without any substantial change in style.
