The First Book

original: "Vergelijcker," a geometric device or diagram used to find equivalent proportions between different scales or body parts.

Thereafter, I determine the length of the Arm as follows: from the joint of the shoulder original: "orels," likely referring to the shoulder or axilla joint, which is positioned at the height of the hollow of the neck original: "hals-kuyl," the suprasternal notch at the base of the throat, to the Elbow, is two-elevenths parts; but from the shoulder joint to the end of the armpit original: "orels-vleesch," literally 'shoulder-flesh' or the axillary fold is one-tenth part. From the Elbow to the end of the fingers is one-fourth part; from the end of the fingers backward to the end of the hand the wrist joint is one-tenth part, though whoever wishes may make it one-ninth part long. The lengths of the Limbs original: "Lidtmaten" are indicated above.
