LEONARDO DA VINCI - Studies for the construction of a model leg
Royal Collection (RLW), 12619r; K/P 152r
This sheet offers an extreme example of Leonardo's favorite technique of portraying muscles as ropes or strings to show their lines of force. Here, he actually suggests moving up from a plain drawing to a model of the limb in which the muscles are represented by copper wires. The model would help to produce anatomical drawings of greater demonstrative efficiency than those obtained from the direct observation of the dissected limb. The drawings show three views of the model, but the annotations refer to a fourth drawing (the rear view of the leg), missing here.
