ABSTRACT
Anatomy was being studied at the same time as pose; the artist wished to acquire a knowledge of the internal structures as well as of the outer form. The human body which he had occasion to observe in many different poses interested him also on account of its architecture, the play of the limbs, the articulations and muscles both in repose and in action. He began by independently analyzing its multiple details such as the pectoral muscles, abdomen, hair, eyes, mouth, kneecap, etc.— by studying its grammar before he considered it as a whole, that is to say before he knew how to establish the correct relation between its different parts or the reciprocal repercussions for a given subject and a given attitude.
