Slight divergence of the eyeballs, on the other hand, is characteristic of children and of great thinkers—an item which Schopenhauer forgot to note when he pointed out that genius always retains certain traits of childhood. “Donders,” says Dr. Magnus, “has always observed this divergent position of the eyes in persons who meditate deeply. And the artists make use of this position of the eyes to give their figures the expression of a soul averted from terrestrial affairs, and fixed on higher spiritual objects. Thus the Sistine Madonna has this divergent position of the eyes, as well as the beautiful boy she carries on her arm.” It is also found in Dürer’s portrait of himself, and in a bust of Marcus Aurelius in the Vatican.

If, however, this divergence becomes too great, it loses its charm, for the eyes then appear to fix no object at all, and the gaze becomes “vacant,” as in the eyes of the blind or the sick. To appreciate the force of these remarks it must be borne in mind that there is only one part of the retina, called the “yellow spot,” with which we can distinctly fix an object. What we see with other parts of the retina is indistinct, blurred.

These details are here given because many will be glad to know that by daily exercising the muscles of the eyeballs before the mirror, they can greatly alter and improve their looks. Every day one hears the remark, “She has beautiful eyes, but she does not know how to use them.” When we read of a great thinker, like Kant, fixing his gaze immovably on a tree for an hour, we think it quite natural; nor does any one object to “the poet’s eye, in a fine frenzy rolling,” for we all know that a poet is merely an inspired madman. But a young lady who wishes to charm by her Beauty must learn to fix her wandering eyes calmly on others, while avoiding a stony stare. One of the greatest charms of American girls is their frank, steady gaze, free from any tinge of unfeminine boldness. Such a charming natural gaze can only be acquired in a country where girls are taught to look upon men as gentlemen, and not as wolves, against whom they must be guarded by dragons.

Eye-gymnastics are as important to Beauty as lung-gymnastics to Health, and dancing-lessons to Grace. But of course there is a certain number of fortunate girls who can dispense with such exercises, because they gradually learn the proper use of their eyes, as well as general graceful movements, from the example of a refined mother.

Goldsmith’s pretty line about “the bashful virgin’s sidelong looks of love,” is not a mere poetic conceit, but a scientific aperçu; for, as Professor Kollmann remarks, “the external straight muscle of the eye was also called the lover’s muscle, musculus amatorius, because the furtive side-glance is aimed at a beloved person.”

Nor is this the only way in which the movements of the eyeball are concerned with Romantic Love. By constantly exercising certain muscles of the eyeball in preference to others, the eyes gradually assume, when at rest, a fixed and peculiar gaze which distinguishes them from all other eyes. It is comparatively easy to find two pairs of eyes of the same colour or form, but two with the same gaze, i.e. characteristic position of the eyeballs, never. Hence Dr. Magnus boldly generalises Herder’s statement that “Every great man has a look which no one but he can give with his eyes,” into the maxim that “Every individual has a look which no one else can make with his eyes.”

Bungling photographers commonly spoil their pictures by compelling their victims to fix their eyes in an unwonted position. The result is a picture which bears some general resemblance to the victim, but in which the characteristic individual expression is wanting.

Our habit of masking our eyes alone when we wish to remain unrecognised, and leaving the lower part of the face exposed, affords another proof of the assertion that the eye is the chief seat of individuality. For though the eyeball itself remains visible, the surrounding parts are covered, so that its characteristic position cannot be determined.

Now we know that Individual Preference is the first and most essential element of Romantic Love. Hence Dante was as correct in calling the eyes “the beginning of Love,” as in terming the lips “the end of Love.” And Shakspere agrees with Dante when he speaks of “Love first learned in a lady’s eyes”; and again: “But for her eye I would not love her; yes, for her two eyes.”

(e) Movements of the Eyelids.—Although the foregoing pages considerably qualify Dr. Magnus’s thesis that the eyeball owes all its life and expressiveness to the movements of the eyelids and brows, yet the physiognomic and æsthetic importance of lids, lashes, and brows can hardly be too much emphasised. A very large proportion of the pleasure we derive from beautiful eyes is due to the constant changes in the apparent size of the eyeball, and the gradations in its lustre, produced by the rapid movements of the upper lid. This is strikingly proved by the fact, noted by Dr. Magnus, “that the eyes of wax figures, be they ever so artistically finished, always give the impression of death and rigidity,” whereas “artificial eyes, such as are often inserted by physicians after the loss of an eye, have, thanks to the constant play of the lids, an appearance so animated and lifelike that it requires the trained eye of a specialist to detect the dead, lifeless glass-eye in this apparently so animated orb.”
