Believed to have been copied at York, in the north of England, about 1364, this "belt book" (a finger-tip reference work in the form of a small fan of folded parchment) includes two visual guides to treatment. The first image facilitated therapy by indicating points at which the practitioner could effectively tap his patient's blood. The second image is designed to help the physician make a diagnosis by analyzing the color of a patient's urine. Owned by the Rosenbach Museum and Library.
