Medieval medical practitioners often integrated celestial observations into their diagnostic and therapeutic practices. This involved correlating the positions of planets and stars with bodily humors and diseases, believing that celestial movements influenced earthly affairs, including human health. For instance, bloodletting, a common medical procedure, was often timed according to lunar cycles. Specific celestial bodies were also associated with particular organs and ailments; Mars, for example, was linked to the liver and conditions like fevers.
This celestial influence on medical practice stemmed from the prevailing philosophical and cosmological frameworks of the time. The humoral theory, originating in ancient Greece, posited that health depended on the balance of four bodily fluids: blood, phlegm, yellow bile, and black bile. These humors were believed to be connected to the four elements (earth, air, fire, and water), which in turn corresponded to celestial bodies. This interconnectedness provided a rationale for using astrological charts to diagnose illnesses and prescribe treatments, offering a structured system in a world where medical understanding was still developing. The practice also reflected the limited scientific knowledge available, with observation of natural phenomena, including celestial movements, serving as a primary means of understanding the world.

2. Humoral Theory Integration
Humoral theory provided the foundational framework for understanding health and disease within the medieval medical system, deeply interwoven with astrological principles. This theory posited that the body contained four humorsblood, phlegm, yellow bile, and black bilecorresponding to the four elements (air, water, earth, and fire) and possessing distinct qualities (hot, cold, wet, and dry). Maintaining a balance of these humors was considered essential for health, while imbalances were believed to cause illness. Astrology played a crucial role in this framework by linking celestial bodies to specific humors and their associated qualities. For example, Mars, a hot and dry planet, was associated with yellow bile (choler), while the cool and moist Moon was linked to phlegm. Planetary movements and alignments were thought to influence the balance of humors within the body, thereby affecting health and disease. This integration provided a rationale for using astrology in diagnosis and treatment.
The practical significance of this humoral-astrological integration manifested in various medical practices. Physicians would consult astrological charts to determine a patient’s humoral predisposition based on their birth date and the planetary positions at the time. Treatments aimed to restore humoral balance, often incorporating astrologically-chosen herbs, minerals, or procedures timed according to planetary cycles. Bloodletting, for instance, might be scheduled during a specific lunar phase to maximize its effectiveness in reducing excess blood or heat. Dietary recommendations also followed humoral principles, with foods classified according to their elemental and humoral qualities to support a balanced constitution. Furthermore, the association of specific planets with particular organs and diseases influenced diagnostic interpretations and therapeutic choices. For instance, an affliction of the liver, associated with Jupiter and the sanguine humor, might be treated with remedies believed to strengthen Jupiter’s influence or reduce excess blood.
Integrating humoral theory with astrology offered a comprehensive, albeit pre-scientific, model for understanding health and illness during the Middle Ages. While later scientific advancements led to the rejection of humoral theory and its astrological underpinnings, studying this system provides valuable insights into the medical beliefs and practices of the time.
