Presently, during one of the intervals that his eyes were open, he saw, within touch of his hand, Agrippa and Caligula side by side, talking to a gladiator. The emperor scowled and looked away. The bearers plodded on, rounded the upper end of the ellipse and, passing down the side, neared the mouth of the cunicula. Agrippa and Caligula had moved from their position and were there, with a notary taking down the terms of a wager. Apart from them stood a small but important man, frowning over a waxen tablet which a slave had cringingly handed him. Tiberius looked at him, then at Agrippa. His brows lowered more, this time with irritation. It seemed that action had been formulated by circumstance and that the emperor was not to avoid a tiresome prosecution. He put out his hand as the bearers bore him by and it touched the Roman on the shoulder. The man turned on his heel, but seeing who was near bowed profoundly. If he meant to speak to the emperor he was not given opportunity. "Bind that man, Macro," Caesar said, nodding at Agrippa. The lectica moved on. As it passed up the opposite side Macro crossed to it and, puzzled and disturbed, bowed again. "Caesar's pardon, but whom am I to bind?" he questioned. "That man," Tiberius replied irritably, pointing to the Herod. "Agrippa!" the astonished prefect exclaimed. "I have said." The lectica went on, up and around the curve of the ellipse, and back again to the cunicula. The few within the walls of the Hippodrome had gathered there in an interested and excited group. In the center stood Agrippa with manacles on his wrists and ankles. The charm and sparkle in his atmosphere were gone; even as Tiberius looked, he saw the cold, evil, vengeful countenance of the Asmonean Slave, the Terror of the Orient, Herod the Great, appear, like a face putting off a mask, behind the graceful features of his grandson. Tiberius was grimly satisfied; he felt the first interest in the arrest; he was always by choice a preferrer of noble game. On either side of the prisoner stood a Roman soldier; aloof and passive was Macro, but the earth had apparently opened and swallowed Caligula. As the lectica approached, the crowd gave way and his captors permitted Agrippa to come nearer the emperor. "At Caesar's command, I am arrested," he said evenly. "Will Caesar grant me the prisoner's privilege and tell me why?" "Thy charioteer hath spoken, Agrippa," was the response. "The slave swears that on such and such a day he drove thee and Caligula to this place. Instead of horses you talked of kings, instead of bets, the succession. And thou madest moan that I was not dead so that Caligula could reign in my place!" The jaws of many round about relaxed in horror. Agrippa's muscles made an involuntary start, but his face retained its calm. But the emperor caught the start. "Forgot that unctuous bit of tittle-tattle when thou didst make Antonia bearer of thy boasts, eh?" he piped.
