Look at Fig. 99, which shows a very attractive group of Ciociari or Neapolitan peasants.

The man, or rather the beardless youth who is just beginning to feel himself a man, and therefore hopes for independence, holds his head proudly level; but the very pretty woman seated beside him holds her head gracefully inclined forward. For that matter, this is woman's characteristically graceful attitude. She never naturally assumes, nor does the artist ever attribute to her the proud and lofty attitude of the level head. But this graceful pose is in reality nothing else than the pose of slavery. The woman who is beginning to struggle, the woman who begins to perceive the mysterious and potent voice of human conflict, and enters upon the infinite world of modern progress, raises up her head—and she is not for that reason any the less beautiful. Because beauty is enhanced, rather than taken away, by this attitude which to-day has begun to be assumed by all humanity: by the laborer, since the socialistic propaganda, and by woman in her feministic aspirations for liberty.

Similarly in the school, if we wish to induce little children to hold their heads in the position of orientation, all that is necessary is to instil into them a sense of liberty, of gladness and of hope. Whoever, upon entering a children's class-room, should see their heads assume the level pose as if from some internal stimulus of renewed life, could ask for no greater homage. This, and nothing else, is certainly what will form the great desire of the teacher of the future, who will rightly despise the trite and antiquated show of formal respect, but will seek to touch the souls of his pupils.

To return to our lines, it follows that the level orientation is the true human position for the head; it ought never to be abased nor carried loftily, because man ought never to make himself either slave or master; it is the normal line, because it should be that of the accustomed attitudes; because man cannot normally be perpetually meditating, with his gaze upon the ground, as if forgetful of himself and of his social ties; nor can he forever gaze at the heavens, as though drawn upward by some supernal inspiration. The normal attitude is that of the thinking man, who cannot lean either in the one direction or the other, because he is so keenly conscious of being in close connection with all surrounding humanity; and he looks with horizontal gaze toward infinity, as though studying the path of common progress.

Now, if from the metopic point of the forehead, we drop an imaginary perpendicular to the line of orientation, it ought to form, in projection, a tangent to the point of attachment of the nostrils. Observe the two lines traced on the profile of Pauline Borghese.

This line, if prolonged, passes slightly within the extreme angle of the labial aperture, and forms the limit of the chin (see the portrait of Cavalieri, Fig. 101). In this case the profile is eurygnathous.

When the line does not pass in the aforesaid manner, but the facial profile protrudes beyond it, we have a case of prognathism, which may be total, when the whole face projects; maxillary when the mandibles project, nasal when it is only the nose that projects, and mental (or progeneism) when it is only the chin that protrudes.
