I'm a little lost but from wiki:
A barber surgeon was a person who could perform minor surgical procedures such as
bloodletting,
cupping therapy or pulling teeth. Barbers could also bathe, cut hair, shave or trim facial hair, and give
enemas.
Personally I use a 'stylist'.
In Medieval Europe medical practice was based on the theory of the
balance of humors. If all was in balance, then health, imbalance then ill health.
Bleeding was often thought to be required to return balance. This of course usually made matters worse.
Anyhow the doctors of "Physic" pronounced on the balance of the humors, and the barbers were called on to do the bleeding. Gradually the practice of surgery grew out of the guild of barbers.
So an aspiring medic could get a medical qualification from the college of physicians, or a surgical one from the Barbers.
It was not until 165 years ago the college of physicians and surgeons combined to set standards for training and granted the primary medical degree jointly.
Even now as soon as a medical graduate chooses a surgical specialty and starts his surgical training he drops the prefix Dr and returns to Mr. His training and further qualifications are then granted come under the purview of the Royal College of Surgeons.
This is just one of numerous ways the UK continues to relive its history.
The Royal College of Surgeons contains the
Hunterian Museum, which is now open to the public and well worth a visit.
So Temple Church lies in a very historic district of London, with close ties to law and medicine, or specifically the practice of surgery.
