Hippocrates & Galen
Hippocrates
He developed the idea of clinical observation of the patient, rather than just of illness itself.
His ideas also resulted in the Hippocratic Oath, which became a code of conduct for doctors. It says that you should do your patients no harm.
-
He was a physician in ancient Greece (460 BC-370 BC) who is considered one of the most outstanding figures in the history of medicine or 'The Father of Modern Medicine' as he was the first with a natural approach to medicine.
Galen
-
-
He trained as a doctor to gladiators and was able to increase his knowledge of human anatomy while treating wounds.
Dissection of human bodies was banned, Galen dissected animals. (Obviously human anatomy is not entirely the same as animals). He thought: the left kidney was higher than the right; blood was made in the stomach and burned as fuel in 12 hours; the human jaw had 2 bones; that blood moved through invisible pores in the heart from side to side; and the liver had 5 parts. He was wrong on all of these. However, he was correct that the brain controlled the body.
Many of his books survived the fall of the Roman Empire so his ideas lasted through the Middle Ages and into the Renaissance. His work formed the basis for doctors’ training for the next 1400 years.
The Theory of The 4 Humours and Opposites 
Hippocrates came up with the theory of 4 Humours; the body was made up of blood, phlegm, yellow bile and black bile.
Pain would occur in the body if one of the substances was either deficient or in excess -> a healthy body needed to keep the 4 Humours in balance.

Galen believed in and developed the theory. This led to a continuity in medical knowledge and practice.
