Ga′len·ist adj. & n.
Galenism Medical theory and practices as taught by the Greek physician Claudius Galen ca. 130–200. Galen brought some science into medicine but was mistaken in many of his ideas. His influence was so great that for 15 centuries it was considered heretical to question his dicta. Many important advances, such as the concept of the circulation of the blood and the appreciation of the dangers of blood-letting, were thereby delayed.
