The metaphorical and mythical use of the kidney in antiquity

Abstract:
While the Syrians and the Arabs viewed the liver as the center of life, the kidneys, in contrast, held a primary place of importance in Israel. In Hebrew tradition, they were considered to be the most important internal organs along with the heart. In the Old Testament most frequently the kidneys are associated with the most inner stirrings of emotional life. But they are also viewed as the seat of the secret thoughts of the human; they are used as an omen metaphor, as a metaphor for moral discernment, for reflection and inspiration. This field of tension in metaphoric usage is resolved under the conception of the kidneys as life center. In the Old Testament the kidneys thus are primarily used as metaphor for the core of the person, for the area of greatest vulnerability. For us today, this metaphorical use of the kidneys has lost its meaning. One reason for its disappearance is certainly the monopoly of causal-analytic rationality in science of today. The kidney has developed from myth to organ, and with this transition a variety of perspectives and ways of looking at knowledge inherent in imaginative thought have been lost. But the metaphor uncovers a deeper level of truth, it represents another form of reconstruction of reality which needs not necessarily be subordinate to the scientific rationality. Today as well, these imaginative ideas can provide an approach to an essential level of reality which may otherwise remain hidden.

Kidney Structure
Introduction to Urinary System
The kidneys are bean-shaped organs located in the retroperitoneal space, on either side of the vertebral column, between the T12 and L3 vertebrae. They are partially protected by the rib cage and surrounded by perirenal fat, which provides cushioning. They are responsible for urine formation and play critical roles in regulating blood pressure, electrolyte levels, and hormone production. The ureters...
External Anatomy of the Kidney
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
