ON DRAWING
Designated D, and the other following marked E, some turn upwards in the shape of an Arc, and others downwards. This difference is more pronounced in a Column that is shaded above and below the Horizon, especially if one understands Perspective. Thus, for the present, it is enough to know the circumstances under which to vary the hatches and get accustomed to the hand, since this is essential to beautiful technique. However, one must be careful to observe that this is not the only thing to consider, and a precise and bold Contour is equally essential to a Work, which, without it, would become useless and of no value.
NINTH LESSON
After discussing Heads, Hands, and Feet, as well as handling the red Chalk, we will proceed cautiously to complete Figures. I present my Students with another Example, so they can observe the structure of solid limbs and their connections. They will sketch these two Figures in large, or their main parts, with charcoal; using only light, yet precise lines, starting with the standing one. Also, they must always start from the right side of the Figure, as the initial lines are always exposed to the eye, and the rest follows more naturally, with less effort, instead of starting from the left side where the hand obstructs the object and prevents it from being seen. Even before a young Student applies his Charcoal to paper, it is appropriate and very advantageous for him to hold his Model in hand for some time, closely observing with all possible attention, taking care of how the Figures and their connections appear.
