Recto: studies of musculature in the right arm; the head of an old man, resembling a recumbent effigy; a diagrammatic drawing of the jaw; a study of a left arm, showing the veins; veins of the body and the right arm; a detailed drawing of the basilic vein and tributaries; notes on the drawings. Verso: four studies of the right shoulder and arm; a slight study of the elbow; a front view of an open mouth, showing molar teeth, palate, uvula and throat; notes on the drawings. In the winter of 1510-11 Leonardo was apparently working in the medical school of the University of Pavia, alongside the professor of anatomy Marcantonio della Torre. He may have dissected up to 20 human bodies that winter, and the elderly and apparently dead man depicted at the top of this page (RCIN 919005r) was presumably the subject of one of Leonardo’s dissections. His investigations focussed on the mechanisms of the bones and muscles, and he developed novel illustrative techniques to convey the complexity of these mobile, layered, three-dimensional structures. Following his first efforts in anatomy around 1490, Leonardo returned to the subject around 1506. He intended to publish an illustrated treatise on the subject, but this was never completed, and the work of one of the great anatomists of the Renaissance thus had no discernible impact on the discipline.
