"The pages of this book tell about the human body, which consists of voluminous blocks: their twisting, twisting and turns, united by a common rhythm, give the drawing a sense of movement. Various stages of learning in sequence are presented here, ranging from the section "How to draw a human body" to "The ratio of light and shadow." This arrangement of material is given in order to awaken in the artist the desire to explore and analyze the structure of the body hidden by the muscles." D. B. Bridgeman.
