The prefect knew his master well, and watched his every expression while apparently listening to the voluble physician, but in reality absorbed in a train of thought. By the twitching of his eyelids, the sharply outlined red patches on his cheeks, the quivering nostrils, and the deep furrows between his eyes, he must be revolving some frightful plan in his mind.
Yesterday, had he found him in this condition, Macrinus would have endeavored by every means in his power to calm his wrath; but to-day, if Caesar had set the world in flames, he would only have added fuel to the fire, for who could more surely upset the firmly established power of this emperor and son of emperors as Caracalla himself? The people of Rome had endured unimaginable sufferings at his hands; but the cup was full, and, judging from Caesar’s looks, he would cause it to overflow this day. Then the rising flood which tore the son of an idolized father from the throne, might possibly bear him, the child of lowliness and poverty, into the palace.
But Macrinus remained silent. No word from him should change the tenor of the emperor’s thoughts. The plan he was thinking out must be allowed to ripen to its full horror. The lowering, uncertain glance that Caracalla cast round the tablinum at the close of the physician’s narrative showed that the prefect’s reticence was an unnecessary precaution.
Caesar’s mind and tongue still seemed paralyzed; but at that moment something occurred which recalled him to himself and brought firmness to his wandering gaze.
There was a sudden disturbance in the antechamber, with a confused sound of cries and shouting. Those friends of Caesar who wore swords drew them, and Caracalla, who was unarmed, called to Antigonus to give him his.
“A revolt?” he asked Macrinus with flashing eyes, and as if he wished the answer to be in the affirmative; but the prefect had hastened to the door with drawn sword. Before he reached it, it was thrown open, and Julius Asper, the legate, burst into the tablinum as if beside himself, crying: “Cursed den of murderers! An attempt on your life, great Caesar; but we have him fast!”
“Assassination!” interrupted Caracalla with furious joy. “That was the only thing left undone! Bring the murderer! But first”—and he addressed himself to Aristides—“close the city gates and the harbor. Not a man, not a ship must be let through without being searched. The vessels that have weighed anchor since daybreak must be followed and brought back. Mounted Numidians under efficient officers must scour the high-roads as soon as the gate-keepers have been examined. Every house must be open to your men, every temple, every refuge. Seize Heron, the gem-cutter, his daughter, and his two sons. Also—Diodoros is the young villain’s name?—him, his parents, and everybody connected with them! The physician knows where they are to be found. Alive, do you hear?—not dead! I will have them alive! I give you till midnight! Your head, if you let the jade and her brothers escape!”
With drooping head the unhappy officer departed. On the threshold he was met by Martialis, the praetorian centurion. After him, his hands bound behind his back, walked the criminal. A deep flush overspread his handsome face, his eyes glowed under the too lofty brow with the fierce light of fever, his waving locks stood out in wild confusion round his head, while the finely cut upper lip with its disdainful curl seemed the very seat of scorn and bitterest contempt. Every feature wore that same expression, and not a trace of fear or regret. But his panting breast betrayed to the physician’s first glance that they had here to deal with a sick man in raging fever.
They had already torn off his mantle and discovered beneath its folds the sharp-edged butcher’s knife which plainly betrayed his intentions. He had penetrated to the first antechamber when a soldier of the Germanic body-guard laid hold on him. Martialis had him by the girdle now, and the emperor looked sharply and mistrustfully at the praetorian, as he asked if it were he who had captured the assassin.
The centurion replied that he had not. Ingiomarus, the German, had noticed the knife; he, Martialis, was here only in right of his privilege as a praetorian to bring such prisoners before great Caesar.
