The Zodiac Man, or man of signs, links each astrological sign with a portion of the human body. This idea, which dates back at least to the medieval period, arises from the concept of the human body as a microcosm of the universe. In some images, including this one, the connection is underscored by having the figure seated on a globe.You can see some wonderful medieval illustrations of the man of signs at the Luminarium Encycopedia project.
According to traditional astrology, the signs could be used to time medical treatment; for example, bloodletting should be avoided when the moon is in the house of the afflicted body part. Ares, the first sign of the zodiac, is associated with "the head and face." and the later signs go with lower portions of the body (Taurus/neck, Gemini/arms, Cancer/breast, Leo/heart, Virgo/bowels, Libra/reins, Scorpio/secrets, Sagittarius/thighs, Capricorn/knees, Aquarius/legs). Pisces, the last zodiac sign, is associated with the feet. By the 18th century, more modern theories of medicine were also available, but almanacs continued to reprint the traditional guide as well.
