Studies of the Leg of a Man and a Horse's Head (recto); sketches of the back of a man's left shoulder and a chained (?) figure.

The detailed explorations of the muscular structure of the human leg, seen from varying points of view in this sheet, attest to the importance of anatomical studies during the Renaissance. In order to better understand the human form, artists such as Leonardo and Michelangelo carried out dissections. The unrelated annotations of accounting information in the right margin were written by a later hand.
