Name Galen

Greek name (Γαληνός) comes from the Greek words (γᾰλήνη) [galini] - "calm, calmness, serenity, tranquility, clarity".

Galen, better known as Galen of Pergamon (129 or 131 - about 200 or 210), was a prominent Roman (of Greek ethnicity) physician, surgeon and philosopher. Arguably the most accomplished of all medical researchers of antiquity, Galen contributed greatly to the understanding of numerous scientific disciplines including anatomy, physiology, pathology, pharmacology, and neurology, as well as philosophy, and logic.
