Restored from Leonardo da Vinci’s c. 1512–13 pen-and-ink manuscript study of avian wing mechanics (Windsor Royal Library RCIN 912656). Traces four progressive stages of wing extension and flexion, exposing the humerus, radius-ulna lever arm, carpometacarpus joints, and the tendon cords that automatically spread the primary flight feathers during the downstroke, accompanied by Leonardo’s left-handed mirror-script notes and proportional scale bars.
