Meaning

Circulus refers to the ring or visible peripheral zone examined in blood and urine within historical inspection practices. It does not mean the circulation of blood through the body. The distinction is especially important because veins and liver appear in the same paragraph: the neighbouring physiological account does not license substituting a later circulatory meaning for this visual noun.
