Facial angle

Definition and stakes

J. W. Redfield,  Popular Science Monthly (1874)

“ Those formed by the front and base lines of the face constitute the facial angle of the upper part of the face, and indicate the degrees of intellectual and artistic development: those formed by the base-line of the face and the axial line of the neck constitute the facial angle of the lower part of the face, and indicate the degrees of affectional and passional development. ”

Various,  Popular Science Monthly (1901)

“ Now, if the angle of the face is taken in connection with the type of head, we have a fairly certain indication of the direction of the plane of vision.
With the long head and strong external facial angle the plane of vision is almost invariably low. With the broad head and inverse angle the visual plane is also low, but there is a restricted downward range of the rotations of the eyes, notwithstanding this depressed position of the visual plane. With the tall head and straight face the plane of vision is high and in proportion as the head is comparatively tall it may be very high.
