The history of medicine in the Middle Ages is a captivating journey through the centuries, marked by significant advances and considerable challenges. This period, which spans from the 5th to the 15th century, saw the emergence of innovative medical practices, the evolution of anatomical knowledge, and the development of a medical ethics influenced by religious precepts. Let us dive into this era where medicine oscillated between science and spirituality, between tradition and innovation.
Sommaire
The evolution of medical practices over the centuries
At the beginning of the Middle Ages, Western medicine experienced a period of stagnation following the fall of the Roman Empire. Medical knowledge was then mainly in the hands of clerics and religious figures, who perpetuated ancient traditions. However, from the 11th century onwards, a revival of medical studies began, marked by the founding of the Salerno school in Italy, considered the first medical faculty in the Western world.
This revival accelerated in the 13th century with the rise of universities. Prestigious institutions such as Montpellier, Bologna, Oxford, Paris, and Padua began to teach medicine systematically. Medieval doctors relied on a corpus of knowledge inherited from Antiquity, notably the works of Hippocrates and Galen, enriched by contributions from Arabic medicine, particularly the works of Avicenna.
The theory of humors, a cornerstone of ancient medicine, remained central in the medieval conception of health and disease. According to this theory, the balance between four humors (blood, phlegm, yellow bile, and black bile) determines an individual’s health status. Therapeutic practices of the time therefore aimed to restore this balance by various means:
- Bloodletting
- Purgatives
- Specific dietary regimens
- Use of medicinal plants
Surgery, long considered a minor discipline, experienced gradual development during the Middle Ages. Medieval surgeons refined their techniques for treating wounds, fractures, and even some more complex operations. In 1363, Guy de Chauliac published his “Great Surgery,” a work that would be a reference for several centuries.
Medical institutions and academic training
One of the notable phenomena of medieval medicine is the multiplication of hospitals from the 11th century onwards. Often founded by religious orders, these establishments played a crucial role in caring for the sick and developing nursing care. The Hôtel-Dieu of Paris, founded in 651, became one of the largest hospitals in Europe, accommodating up to 1,000 patients in the 15th century.
The training of doctors underwent significant evolution with the rise of universities. Medical students followed a rigorous curriculum, combining the study of ancient texts and clinical observation. By the end of the 13th century, despite certain religious restrictions, human dissection began to be practiced in universities, marking a major advance in the understanding of anatomy.
The influence of the Church on medical practice was considerable. It promoted the development of care for the sick, considered an act of mercy, while strictly regulating medical ethics. This influence resulted in the emergence of Christian norms governing the relationship between doctor and patient, as well as debates on ethical issues such as contraception, abortion, or euthanasia.

Diversity of approaches and cultural influence
Medieval medicine is marked by a remarkable diversity of approaches and cultural influences. Arab and Jewish medicine play a crucial role in the transmission and enrichment of ancient medical knowledge. Figures such as Avicenna (980-1037) and Maimonides (1138-1204) contribute significantly to the advancement of medical knowledge, leaving a lasting influence on practice in the West.
Women, although often marginalized in medieval society, hold a notable place in the medical field. Personalities such as Hildegard of Bingen (1098-1179), abbess and author of medical treatises, or Trotula of Salerno (11th century), to whom works on gynecology are attributed, illustrate the female contribution to medicine of the time.
The attention given to hygiene and nutrition is reflected in the many “health regimens” developed in the Middle Ages. These works, mainly intended for the elites, provide detailed advice on diet, physical exercise, and lifestyle habits to maintain good health. The “Regimen Sanitatis Salernitanum,” compiled in the 12th century, became one of the most popular medical texts of the medieval period.
Challenges and limits of medieval medicine
Despite its advances, medieval medicine faced significant challenges, notably in the face of the great epidemics ravaging Europe. The Black Death, which struck the continent in 1347, decimated nearly a third of the European population, highlighting the limits of the medical knowledge and practices of the time.
Medieval physicians, confronted with these scourges, developed innovative approaches to public health. Quarantine measures were established in some Italian cities as early as the 14th century to try to contain the spread of diseases. These initiatives foreshadow modern epidemic control policies.
The history of medicine in the Middle Ages reveals a fascinating period of transition, where ancient traditions and innovations coexist. This era laid the foundations for many modern medical practices, while reflecting the social, cultural, and religious complexities of its time. The legacy of medieval medicine continues to influence our understanding of health and disease, reminding us of the importance of history in the evolution of medical science.
