Medieval almanacs drew the zodiac over the human body to show which star signs governed each organ

the gist

The zodiac man, or Homo signorum, is an image of a human body with each astrological sign linked to a body part. Pisces was tied to the feet, Aries to the head, and Cancer to the chest. Physicians used these charts to time treatments, so bloodletting was avoided when the Moon was in the sign that governed the affected part. A fifteenth-century English almanac in Latin shows a figure with the signs pulling on his limbs. Similar images appear in Persian manuscripts and in colonial-era facsimiles of Mesoamerican artefacts. The idea rested on a belief that the body was a microcosm whose health followed the movements of the heavens.

so what

The zodiac man shows how astrology was once part of medical practice rather than a separate pastime. Medicine later separated from astrology as anatomy and experiment gained ground. The images remain a useful record of how people once explained illness.
