Leonardo analyzed the lower limbs for their power, in view of their possible propulsive energy for operating his machines. The two wax models in the display case represent the lower right limb in kneeling position, that is, with the knee and the tip of the foot resting on the ground. Just as in Leonardo’s drawing, which you can view on the longest wall of the room, the two sculptures highlight two different levels of dissection: one shows the conformation of the surface musculature, while the other depicts the bones and deeper connections between muscles.
