Trephining. Coloured 13th century artwork showing trephining,the drilling of a hole into the skull in order to relieve pressure on the brain. The instrument used,the trephine,was an improved version of the simpler trepan,as it had a guiding centre pin. Medieval doctors prescribed surgery,but thought it too demeaning to actually perform. Instead,surgery was performed by a lower caste of medical practitioners,such as butchers,who had no training other than an apprenticeship with a surgeon | |
