James Romm writes:
How fortunate you would have been, as a Roman patient of the second century AD, to be attended by Galen, the greatest Greek physician of the age. Galen would have paid housecalls, several times a day if needed, and brought you food. He would have questioned you with earnest concern about the onset and progress of your symptoms. He would have supplied medicines mixed from as many as 64 ingredients. And for all this personal attention, you would not have been charged a fee.
