Ancient Medicine

Performing Medicine.
How important was public performance to being a doctor in antiquity?
What do treatises such as the Hippocratic Decorum teach us about the training and thought processes of (at least some) ancient doctors? How does Decorum contrast with modern medical ethics? Are there aspects of it that should be revived? Why or why not?
