The Church, the Monastery and Islamic Medicine
Religion: Engine and Brake
In medieval Britain religion was not a sideshow to medicine — it was the institution that decided which texts survived, who got trained, where the sick were cared for, and what counted as a legitimate cause of disease. Both Christianity and Islam shaped medical practice profoundly. Both pushed progress forward and held it back at the same time. For the 16-mark factor essay, ‘superstition and religion’ is one of the seven AQA factors, and this lesson is where students collect the evidence to weigh it.
The medieval Church both helped medicine (built hospitals, copied Galen’s texts, trained literate physicians) and held it back (banned clergy from cutting open bodies in 1163, framed disease as God’s punishment, blocked rival theories). Religion is therefore a factor that pushes both ways.
The Christian Engine: Hospitals, Care and Texts
By 1500 there were over 700 hospitals in England, almost all founded and run by the Church. Monastic infirmaries provided clean water, herb gardens, structured diets and prayer for inmates. St Bartholomew’s Hospital was founded in London in 1123 by the courtier Rahere; St Thomas’s followed in 1173. Most medieval hospitals were not where you went to be cured — they were places of comfort for the dying, the elderly, lepers, pregnant women and orphans. They were called ‘hospitals’ because the word means ‘a place of hospitality’, derived from Christian duty.
The Church also preserved knowledge. In monasteries from St Albans to Durham, monks copied classical Greek and Roman medical texts by hand. Without that copying work, Galen and Hippocrates would have been lost — the same texts that universities later taught from existed only because of the patient labour of religious scribes. The communication factor and the religion factor here run together: Church-controlled writing was the medium for medical knowledge.
The Christian Brake: Dissection, Sin and Authority
The same Church that preserved Galen also protected him from challenge. In 1163 the Council of Tours banned clergy from cutting open bodies (the famous ‘Ecclesia abhorret a sanguine’ — the Church abhors blood). Although a small number of medical-school dissections were allowed from the early 1300s, routine examination of the dead was rare. Doctors who suspected Galen was wrong had no way to test him. Worse, when illness struck, the Church taught that disease was often divine punishment for sin. The 1349 plague processions of flagellants — people whipping themselves through towns to atone — were a logical response inside the religious framework, but they spread the disease faster.
The Islamic Golden Age
While medieval Europe leaned heavily on the past, the Islamic world was producing its own breakthroughs. In Baghdad, Damascus and Cairo, large state-funded hospitals called Bimaristans treated patients of all faiths free of charge, separated wards by disease, and taught medical students at the bedside. The Persian physician Al-Razi — known in Europe as Rhazes — was the first to distinguish smallpox from measles in writing. His successor Ibn Sina — Avicenna — produced the Canon of Medicine, a million-word encyclopaedia that became the standard textbook in European universities for the next 600 years.
Translation routes were the bridge. From the late 11th century scholars in Toledo (recaptured from Muslim rulers in 1085) translated Arabic medical works into Latin. The medical school at Salerno on the Italian coast was the first European institution to teach Islamic and Greek medicine together. From there, Latin editions of Ibn Sina and Al-Razi reached Oxford and Bologna. By 1300 a physician trained in Britain was studying not just Galen but the Galen-plus-Avicenna package shaped by Islamic scholars.
Islam itself encouraged medicine: the Prophet’s teaching ‘For every disease, Allah has given a cure’ gave religious endorsement to the search for treatment. Unlike the Christian Church, Islamic teaching did not generally restrict dissection.
Medieval Surgery: More Than Cauterising and Praying
Surgery in medieval Britain was performed by barber-surgeons rather than physicians. Standard procedures included setting broken bones, removing arrowheads, cauterising wounds with a hot iron, treating boils, and trepanning — drilling a hole in the skull to relieve pressure. Pain relief was crude: alcohol, opium, or a mixture called ‘dwale’ made from hemlock, opium and lettuce juice that could either sedate or kill the patient.
Significant individuals pushed surgical practice forward despite the limitations of their period. John of Arderne, working in the 14th century, developed an effective treatment for anal fistula and produced detailed surgical writings illustrated with case histories. Hugh and Theodoric of Lucca argued in the 13th century that wounds healed better when kept clean — an idea that put them centuries ahead of mainstream practice and contradicted the dominant view that pus was a healthy sign of healing. These individuals show how the role-of-the-individual factor produced isolated breakthroughs even when the broader system was static.
Al-Razi (c854-925) wrote the first clear distinction of smallpox from measles. Ibn Sina (980-1037) compiled the Canon of Medicine, used as the standard European textbook for over 600 years. Both shaped how British physicians were trained.
Linking to the Factor Essay
When the 16-mark question names ‘superstition and religion’ or ‘communication’ as the factor, this lesson supplies the strongest medieval evidence. Religion built hospitals and preserved Galen but blocked dissection. Communication routes through Toledo and Salerno carried Islamic improvements to Britain. The role of the individual produced Al-Razi, Ibn Sina, John of Arderne. Strong answers will keep returning to the named factor — not list every figure they know.
