At this point they were interrupted, for Martialis pointed to a tall man who was coming toward them, and whom his sharp eye had recognized as Macrinus, the prefect of the praetorians.  In an instant the soldiers were erect and rigid, but still many a helmeted head was turned toward the spot where their chief stood talking in an undertone to the Magian Serapion.

Macrinus had persuaded Caesar to send for the exorciser, to test his arts.  Immediately after the performance, however late it might be, the Magian was to be admitted to his presence.

Serapion thanked the prefect, and then whispered to him, “I have had a second revelation.”

“Not here!” exclaimed Macrinus, uneasily, and, leading away his handsome little son, he turned toward the entrance.

Dusk, meanwhile, had given way to darkness, and several slaves stood ready to light the innumerable little lamps which were to illuminate the outside of the Circus.  They edged the high arches which surrounded the two lower stories, and supported the upper ranks of the enormous circular structure.  Separated only by narrow intervals, the rows of lights formed a glittering series of frames which outlined the noble building and rendered it visible from afar.

The arches on the ground-floor led to the cells from which the men and beasts were let out into the arena; but some, too, were fitted with shops, where flowers and wreaths, refreshments, drinks, handkerchiefs, fans, and other articles in request, were sold.  On the footway between the building and the row of pitch torches which surrounded it, men and women in thousands were walking to and fro.  Smart, inquisitive girls were pushing their way singly or in groups, and their laughter drowned the deep, tragical voices of the soothsayers and Magians who announced their magic powers to the passersby.  Some of these even made their way into the waiting-rooms of the gladiators and wrestlers, who to-day so greatly needed their support that, in spite of severe and newly enforced prohibitions, many a one stole out into the crowd to buy some effectual charm or protecting amulet.

Where the illuminations were completed, attempts of another kind were being made to work upon the mood of the people; nimble-tongued fellows—­ some in the service of Macrinus and some in that of the anxious senate—­ were distributing handkerchiefs to wave on Caesar’s approach, or flowers to strew in his path.  More than one, who was known for a malcontent, found a gold coin in his hand, with the image of the monarch he was expected to hail; and on the way by which Caesar was to come many of those who awaited him wore the caracalla.  These were for the most part bribed, and their acclamations were to mollify the tyrant’s mood.
