In the moonlight it seemed to him that during his thirty years of absence the image had grown larger. That his eyes, accustomed to watch for unexpected perils, played him no tricks he was certain, yet he now observed the brow of the Sphinx to be wreathed in a faint vapour as if its crest had attained the altitude of no inconsiderable hill. The fissures between the stones seemed slightly to have filled, but the crevices across the face were both more numerous and more deeply scored. The pits of the eyes, too, had become immensely more cavernous. And--could he be mistaken?--was not the smile less ambiguous? Surely he did not remember the visage as so noble, or had it grown nobler in his absence? How was it that, though the aspect remained as unflinching as ever, the expression now seemed less hard and more magnanimously stern? The cheeks had undoubtedly sunk further, but did not the muscles appear tightened less in impatience than in endurance of suffering? The nostrils no longer breathed scorn; they laboured with the indrawing of breath that, like fire, was at once painful and inspiriting. To the brow there had been added, he thought, a faint line, and its coming had softened the contraction of the brows so that the creature appeared even more majestic and wiser than of yore. And lastly--he took long to discover this--in the shadow under the brows the orbs seemed to stir with a mysterious and darkling life. "O mighty Sphinx," he murmured, leaning his head upon her bosom, "what has come to thee? How art thou changed! Much I fear thou hast passed beyond so small, feeble, and ignoble an intelligence as I and that now I shall never learn the secret that, behind thy lips, lies locked in thy heart. O Sphinx, if I speak wilt thou answer? Time was when I came to thee and, impatiently stamping my foot upon the mound of thy illimitable desert, beating with my fists thine unanswering flesh, conjured thee in a voice of thunder to yield up thy secret. But to-night, nestling against thy bosom, how shall I speak to thee?--I, of less account among men than one of the myriad morsels of dust out of which thou art compounded; I, whose voice is to thine ears hardly louder than the scratch of the beetles that crawl about thy base; I, lost in the shadowy cleft between thy breasts? O Sphinx, I will not cry out to thine unregarding face, lost in such a reverie as transcends the thought of such as myself, but leaning here my fevered forehead against thy cool stones, as in a dream and scarcely expecting an answer, let me whisper to thy heart, '_What is the secret of thy smile, O Sphinx?_'" Then from within the Sphinx arose a deep murmuring as of a multitude of nigh-forgotten voices; a handful of vapour parted from the lips to wither in the glacial moonshine. "Scarcely am I changed," said the Sphinx. "'Tis thou art changed. Look in thy heart: there is my secret."
