THE FIRST PART

Your figure will not serve you, nor represent other things, if the face changes sides. Some parts will be more elevated, and others less, thus I will show you that the lower part of the face in profile, as demonstrated by the letters A B C, indicates the posture. B C will hang a bit more, but with the letter C, you will find it bends to another side. In making the figure, it is necessary to observe the lines from which the nose and mouth rise, as is evident by the figure with letters D E F, which shows the outline more extended, and thus learn to make the measures correctly.

These figures do not show much of anything, if they do not vary from other forms: whether they rise more than others or recede. But I will now show the outlines of the half-faces equally by the letters A B C, which are not much higher in profile. But C bends to another side when presenting these figures. One must watch the line. Look, as the letters D E F indicate, here I talk more about how to handle them. This general knowledge is the groundwork of good measurement.

This figure shows only a slight change in the view of objects, one more than the other. Some are a bit more elevated, others less; but I will now show only a little; the ABCs of faces in profile, as shown by the letters A B C. B C looks down a bit, but C leans to the other side, so if someone wants to make such figures, they have to pay attention to lines and how the nose and mouth are aligned, as shown by letters D E F. This matter I hope to address more fully later, but for now, this is enough to learn the measurement.

Translation Notes:

- "Variar delle fuisse" translates to "change of sides," indicating the shifting profiles of the face.
