With regard to the _form_ of the eye in ideal sculpture it is large of size, widely extended, oval and in respect to position placed at right angles toward the line of the forehead and nose, and in considerable depression. As far back as Winckelmann[160] the large size of the eye was accounted significant of beauty, just as a great light is more beautiful than a small one. "The size, however," his description continues, "is relative to the bone of the eye or its cavity, and is expressed in the mode of incision[161] and in the opening of the eyelids, of which in beautiful eyes the upper describes a more circular arch toward the angle within than the lower one." In the case of profile heads of superior workmanship the apple of the eye itself possesses a profile and receives precisely by virtue of this opening thus cut away a nobility and a free glance, whose very light, according to Winckelmann's observation, is rendered visible on coins through an exalted point or focus on the apple of the eye. At the same time mere size does not make all eyes beautiful; they are this in the first place by virtue of the cast of the eyelids, and in the second through being themselves deepset. In other words the eye ought not to press forward, and by so doing be thrust on the external world, for it is just this close relation to the external world which is removed from the ideal, exchanging for this the self-retirement of personality upon its own resources, that is, upon what is ideally substantive in the individuality. The projection of the eye, however, also suggests the thought that the apple of the eye is at one time pushed to the fore and at another withdrawn, and, particularly in the case of the staring gaze, only testifies to the fact that the individual is beside himself, either staring in total absence of thought, or in an equally soulless way absorbed in the gaze upon some material object. In the Ideal of antique sculpture the eye is placed in even more pronounced retreat than we actually find it in Nature. Winckelmann suggests as a reason for this that in the case of statues of larger size which are placed more remote from the vision of the spectator, without this more receding position, on account of the fact that apart from this the apple of the eye was for the most part flat, the eye itself would have been without meaning and practically lifeless, if by just this more emphatic projection of the bone of the eye-socket, the thereby accentuated play of light and shadow had not made the eye more apparently active. Yet this deepening of the eye has a yet further significance. In other words, if the forehead is thereby suffered to receive a prominence superior to that of Nature the contemplative portion of the face is the predominant factor, and we receive a keener sense of spiritual expression, while also the emphasized shadow in the eye-sockets on its own account enables us to feel a depth and
