The Zodiac Man: Influence of Astrology
The Zodiac Man is a medieval astrological image which is found in many medieval manuscripts. The image of the Zodiac Man is a diagram illustrating the influence of the twelve astrological signs over different parts of the human body. It was believed that each of the twelve signs of the zodiac presided over different parts of the body. For instance, Aries presides over the head, face, brain and eyes, whilst Capricorn presides over the knees, joints and the skeletal system. The Zodiac Man would have been used by medical practitioners for both diagnosing patients and determining when a surgical procedure could take place. The purpose of the diagram was to remind medical practitioners which zodiac signs influenced each human body part. This was especially important for determining when a surgical procedure could take place as the position of the moon determined when surgery could be conducted. It was believed that position of the moon in relation to the twelve zodiac signs determined when and where on the human body you can conduct surgery. Interestingly, when the moon is in a specific zodiac sign, the part of the human body which that zodiac sign presides over cannot be treated on, importantly you cannot bloodlet. For instance, when the moon is in Aquarius, practitioners cannot carry out surgery on the ankles, calves, or circulatory system. It is clear, that the image of the Zodiac Man was fundamental to practitioners in determining when to conduct surgery, as it demonstrates clearly which of the twelve zodiac signs preside over each part of the human body. Knowledge of the Zodiac Man was vital for medical practitioners as it was a putative understanding that if surgery was conducted when the moon was positioned in the zodiac which presided over that body part then it was fatal to the patient. It is clear that medical practitioners included the Zodiac Man in their medical manuscripts to demonstrate their understanding of the influence of astrology on the human body, as astrology became an important part of medicine and the understanding of the human body in the middle ages.
