Historical background

Physicians were very highly regarded and respected. Though their positions were deemed prominent it took about a full century before their work was completely accepted.
More skilled than an Apothecarist or Herbalist, the Physician was capable of prescribing new medicines and performing types of surgery. These services were often limited and dependant on the heavy purses of the rich and elite and as such, many a commoner and peasant died simply because they could not afford the services.
The Physician saw much opposition to his career during the 13th Century. Many of his practices such as bleeding, lancing and surgical techniques were deemed to be against the teachings and doctrines of Church Law. Therefore anyone wise enough to know they needed the professional services of a Physician knew also that they could risk punishment or excommunication by the Church.
During the 14th Century though the Church gradually began to accept the merciful work of Physicians and they became wealthy and earned elaborate lifestyles.
