Rogerius (1140 - 1195), also known as Roger of Salerno, brought academic respectability to the discipline of surgery through the hugely popular work on the subject that is attributed to him. Practica Chirurgia or The Practice of Surgery was actually compiled by his students from his lecture notes. Surgery brought about a renaissance in European medical writing and promoted innovations in antiseptic, anesthetic, diagnostic and surgical practices. It describes various activities of the medieval Dispensary, a place where remedies were prepared and applied, diagnoses made and surgeries performed by the doctor and his assistants.
