In 162 AD, Rome's Golden Age reached its peak in territorial expanse and wealth, leading the world in science, culture, philosophy, and medicine. Rome attracted authors, doctors, architects, and philosophers like Galen of Pergamum. Galen, a brilliant medical scientist, was influential in the history of medicine and known for his surviving writings. Eager to impress Emperor Marcus Aurelius, one of Rome's great minds, Galen showcased his skills at the Coliseum.
