Galen |
 | | At the age of 28, Galen was appointed as the physician to the gladiators. |
 | | Galen believed that the authority of ancients was limited to the validity of their claims, and that, while their theories need not necessarily be replaced, they usually required clarification and progression. |
 | | Galen adopted Aristotle's theory of the four humors, which stated that the body is composed of a balance between the four elements present on earth- fire, earth, water, and air- which were manifested in the body as yellow bile, fl bile, water, and phlegm, respectively. |
