What flood of emotions rushed into the vacant mind of Ulpius at the instant when he discerned the long-loved, well-known image of the Egyptian god, there was nothing for some moments outwardly visible in him to betray. His moral insensibility appeared but to be deepened as his gaze was now fixed with rigid intensity on the temple portico. Thus he continued to remain motionless, as if what he saw had petrified him where he stood, when the clouds, which had been closing in deeper and deeper blackness as the morning advanced, and which, still charged with electricity, were gathering to revive the storm of the past night, burst abruptly into a loud peal of thunder over his head. At that warning sound, as if it had been the supernatural signal awaited to arouse him, as if in one brief moment it awakened every recollection of all that he had resolutely attempted during the night of thunder that was past, he started into instant animation. His countenance brightened, his form expanded, he dropped the hand of Antonina, raised his arm aloft towards the wrathful heaven in frantic triumph, then staggering forwards, fell on his knees at the base of the temple steps. Whatever the remembrances of his passage through the wall at the Pincian Hill, and of the toil and peril succeeding it, which had revived when the thunder first sounded in his ear, they now vanished as rapidly as they had arisen, and left his wandering memory free to revert to the scenes which the image of Serapis was most fitted to recall. Recollections of his boyish enjoyments in the temple at Alexandria, of his youth's enthusiasm, of the triumphs of his early manhood--all disjointed and wayward, yet all bright, glorious, intoxicating--flashed before his shattered mind. Tears, the first that he had shed since his happy youth, flowed quickly down his withered cheeks. He pressed his hot forehead, he beat his parched hand in ecstasy on the cold, wet steps beneath him. He muttered breathless ejaculations, he breathed strange murmurs of endearment, he humbled himself in his rapturous delight beneath the walls of the temple like a dog that has discovered his lost master and fawns affectionately at his feet. Criminal as he was, his joy in his abasement, his glory in his miserable isolation from humanity, was a doom of degradation pitiable to behold.
