Esther, excessively strong though apparently fragile, arrested attention by one feature that is conspicuous in the faces in which Raphael has shown his most artistic feeling, for Raphael is the painter who has most studied and best rendered Jewish beauty. This remarkable effect was produced by the depth of the eye-socket, under which the eye moved free from its setting; the arch of the brow was so accurate as to resemble the groining of a vault. When youth lends this beautiful hollow its pure and diaphanous coloring, and edges it with closely-set eyebrows, when the light stealing into the circular cavity beneath lingers there with a rosy hue, there are tender treasures in it to delight a lover, beauties to drive a painter to despair. Those luminous curves, where the shadows have a golden tone, that tissue as firm as a sinew and as mobile as the most delicate membrane, is a crowning achievement of nature. The eye at rest within is like a miraculous egg in a nest of silken wings. But as time goes on this marvel acquires a dreadful melancholy, when passions have laid dark smears on those fine forms, when grief had furrowed that network of delicate veins. Esther’s nationality proclaimed itself in this Oriental modeling of her eyes with their Turkish lids; their color was a slate-gray which by night took on the blue sheen of a raven’s wing. It was only the extreme tenderness of her expression that could moderate their fire. Only those races that are native to deserts have in the eye the power of fascinating everybody, for any woman can fascinate some one person. Their eyes preserve, no doubt, something of the infinitude they have gazed on. Has nature, in her foresight, armed their retina with some reflecting background to enable them to endure the mirage of the sand, the torrents of sunshine, and the burning cobalt of the sky? or, do human beings, like other creatures, derive something from the surroundings among which they grow up, and preserve for ages the qualities they have imbibed from them? The great solution of this problem of race lies perhaps in the question itself. Instincts are living facts, and their cause dwells in past necessity. Variety in animals is the result of the exercise of these instincts.
