And now, before her inward eye, rose the crowd of victims to Caracalla's thirst for blood. She fancied that Plautilla, whom her imperial consort had murdered, was beckoning her to follow her to an early grave. The terrors of the night were too much for her; and, as when a child, at play with her brothers, she flew on as fast as her feet would carry her. She fled as though she were pursued, her long dress hampering her steps, along by the temple wall, till her gaze, fixed on her left, fell on the spot which had been designated to her.

Here she stopped, out of breath; and, while she was identifying the landmarks which she had impressed on her memory to guide her to the right doorway, the temple wall seemed to open before her as if by a charm, and a kind voice called her name, and then exclaimed, "At last!" and in a moment she had grasped Euryale's hand and was drawn into the building.

Here, as if at the touch of a magician's wand, all fear and horror vanished; and, although she still panted for breath, she would at once have explained to her beloved protectress what it was that had prompted her to run so fast, but that Euryale interrupted her, exclaiming: "Only make haste! No one must see that block of porphyry turn on its pin. It is invisible from the outside, and closes the passage by which the mystics and adepts find their way to the mysteries after dedication. All who know of it are sworn to secrecy."

With this she led the way into a dark vestibule adjoining the temple, and in a few moments the great block of stone which had admitted them had turned into its place again. Those who passed by, even in broad sunshine, could not distinguish it from all the other blocks of which the ground-floor of the edifice was built.

CHAPTER XXIX.

While the lady Euryale preceded her young charge with a lamp up a narrow, dark staircase, Alexander waited in one of the audience-rooms till the emperor should call him. The high-priest of Serapis, several soothsayers of the temple, Aristides, the new head of the night-watch, and other "friends" of the monarch had accompanied him thus far. But admittance to the innermost apartments had not been permitted, for Caracalla had ordered the magician Serapion to call up spirits before him, and was having the future declared to him in the presence of the prefect of the praetorians and a few other trusty followers.

The deputation of citizens, who had come to apologize to Caesar for the annoying occurrences in the Circus, had been told to wait till the exorcisms were over. Alexander would have preferred to hold aloof from the others, but no one here seemed to think ill of him for his thoughtless behavior. On the contrary, the courtiers pressed round him —the brother of the future empress-with the greatest assiduity: the high-priest inquired after his brother Philip; and Seleukus, the merchant, who had come with the deputation, addressed many flattering remarks to him on his sister's beauty. Some of the Roman senators whose advances he had received coldly enough at first, now took up his whole attention, and described to him the works of art and the paintings in the new baths of Caracalla; they advised him to offer himself as a candidate for the ornamentation of some of the unfinished rooms with frescoes, and led him to expect their support. In short, they behaved toward the young man as if he might command their services, in spite of their gray hairs. But Alexander saw through their purpose.

Their discourse ceased suddenly, for voices were audible in the emperor's apartments, and they all listened with outstretched necks and bated breath if they might catch a word or two.

Alexander only regretted not having either charcoal or tablets at hand, that he might fix their intent faces on the wood; but at last he stood up, for the door was opened and the emperor entered from the tablinum, accompanied by the magician who had shown Caesar several spirits of the departed. In the middle of the demonstration, at Caracalla's desire, the beheaded Papinian had appeared in answer to Serapion's call. Invisible hands replaced his severed head upon his shoulders, and, having greeted his sovereign, he promised him good fortune. Last of all great Alexander had appeared, and assured the emperor in verse, and with many a flowery phrase, that the soul of Roxana had chosen the form of Melissa to dwell in. Caracalla would enjoy the greatest happiness through her, as long as she was not alienated from him by love for another man. Should this happen, Roxana would be destroyed and her whole race with her, but Caesar's glory and greatness would reach its highest point. The monarch need have no misgivings in continuing to live out his (Alexander's) life. The spirit of his godlike father Severus watched over him, and had given him a counselor in the person of Macrinus, in whose mortal body the soul of Scipio Africanus had awakened to a new life.

With this, the apparition, which, like the others, had shown itself as a colored picture moving to and fro upon the darkened wall of the tablinum, vanished. The voice of the great Macedonian sounded hollow and unearthly, but what he said had interested the emperor deeply and raised his spirits.
