Galen's Methodus Medendi is a collected body of work detailing symptoms and treatments for various ailments that Galen encountered throughout his calling as a physician and surgeon in the Roman Empire in the mid to late second century, during the Antonine Plague. Galen's description of this plague is the leading surce of evidence for many modern scholars who believe that this episode was the first outbreak of smallpox in Europe.
Galen was well respected and was often called on by state officials, at times against his will, to serve as court physician for Commodus and for Septimius Serverus.
