The square measure is also a body of most perfect proportion original: "proportionatissimum". Indeed, if a man is placed standing upright with his arms outstretched and his feet joined together, they constitute an equilateral square, the center of which is at the lowest part of the groin original: "pectinis"; literally "the comb," a term used in Renaissance anatomy to refer to the pubic bone or the pelvic region..

The man’s arms are extended horizontally to the sides, touching the vertical edges of the square, and his feet are together at the base. Two diagonal lines cross the square, intersecting at the man's pubic region, which is marked with a small cross. Above the man's head is a single eye within a circle. To the left of the square is a staff entwined with a serpent The Caduceus, often associated with Mercury/Hermes and the balance of dualities., and to the right is a curved shepherd's crook or lituus A curved wand used by Roman augurs, symbolizing oracular authority.. At the bottom, below the square, is an empty ornamental cartouche with stylized, ribbon-like ends.]
