When the bull was finished, the trainers led it away. A few moments later, from a concealed compartment in the bottom of the effigy, a naked boy wearing a calf’s head jumped out and performed a lively dance.

“The minotaur!” people cried. “She’s given birth to the minotaur!”

The crowd went wild with applause and cheering. Nero beamed with pride.

Such tableaux, one after another, took place all up and down the length of the circus.

Eventually, for a climax, men with torches appeared, and all the Christians who lay lifeless or near to death on the sand and all the wooden props were set afire, though the crucifixes were left untouched. The sight of the flames was alarming, as was the stench of the smoke. Some in the audience, reliving the trauma of the conflagration, wept with grief. Others laughed uncontrollably. There were gasps and shrieks from the crowd, but also cheering and applause. The Christians were convicted arsonists, and the legally prescribed punishment for arson was death by fire.

As the scattered flames died down and night began to fall, sturdy poles twice the height of a man were erected in the spaces between the crucifixes. The poles had been soaked in pitch, as was evident from their strong smell. Obviously, another spectacle involving fire was about to be presented. The crowd reacted with cries of mingled dread and fascination. To the top of each pitch-soaked pole a kind of iron basket was affixed, large enough to hold a human body.

Thus far, Titus had watched the spectacle with grim detachment. The auspices had been unequivocally favourable for this event – Titus had watched closely as Lucan performed the augury – and that was a clear indication that the gods were pleased. Watching the gruesome punishments of the arsonists gave Titus no pleasure, but it was his sombre duty as a citizen and as a friend of the emperor to witness the event.

Titus felt the need to empty his bladder. The moment seemed opportune, as there appeared to be an interlude before the next event, so he rose and excused himself. Looking over his shoulder, Nero told him where to find the nearest latrina and then giggled, as if at some secret joke. Titus left the imperial box, glad that the spectacle had put the emperor in such a buoyant mood.

The latrina was in a small building some distance from the stands. A few other men were inside, talking about the spectacle as they went about their business. They were in general agreement that, while some of the punishments had been too repetitious, others had been quite remarkable. There was an enthusiastic consensus that the rape of Pasiphae had been by far the most impressive of the tableaux.

“Not something you see every day!” quipped one man.

“Unless you’re a god, like Neptune, and can make such things happen with a wave of your trident.”

“Or unless you’re Nero!”

Titus headed back to the stands. The sky had grown darker. The stars were coming out. Torches had been placed here and there to light the grounds. As he neared the stands, a pair of Praetorians abruptly blocked his way.

“What’s that?” said one of them. The man was big and brutish but had perfect teeth, which glinted in the torchlight. He pointed at the fascinum at Titus’s breast. “Isn’t that a cross, like some of those Christians wear?”

“What I wear around my neck is none of your business,” said Titus curtly. He tried to step past the two men, but they barred his way.

“You’ll come with us,” said the Praetorian with perfect teeth.

“I most certainly will not. Can you not see that I wear a senator’s toga? I’m returning to the imperial box.”

“Sure you are! A Christian, in the emperor’s box!”

Each of them grabbed an arm and together they led him, despite his efforts to resist, to a small room under the newly built wooden stands. A third Praetorian, apparently their superior, sat at a table piled high with scrolls.

“Problem?” he asked.

“An escaped Christian, sir,” said the Praetorian with perfect teeth.

“This is ridiculous!” snapped Titus.

“What’s your name, Christian?” said the officer

“My name is Pinarius. Senator Titus Pinarius.”

The officer consulted a list. “Ah, yes, we do indeed have a Pinarius among those scheduled to be punished in the circus today. A male citizen, age forty-seven. This must be him.”

Titus clenched his jaw. All day he had avoided thinking about his brother, telling himself he had no brother. “That would be Kaeso Pinarius, not Titus-”

“ Now I recognize you!” said the officer. “You were one of the first arsonists we arrested. You certainly look different now! How did you manage to clean yourself up like that, and escape from the cell? And where in Hades did you get that toga? I’ll bet you murdered a senator to get your hands on that!”

“This is absurd,” said Titus. “I am a senator, an augur, and a friend of the emperor.”

The Praetorians laughed.

Titus felt a sinking sensation. The situation was getting out of hand. He told himself to remain calm.

“Let me explain something,” he said, speaking though gritted teeth. “I have a brother… a twin brother… who is a Christian-”

The Praetorians only laughed harder.

“An identical twin?” shouted the Praetorian with perfect teeth. “That’s rich!”

“With your imagination, you should be writing comedies for the stage, not setting fires,” said the officer, who abruptly ceased laughing and looked grim. “Such a preposterous story only confirms what I suspected. What do you fellows think? How do we treat a lying, murdering Christian?”

The Praetorians roughly shoved Titus back and forth between them, yanked at his toga until they pulled it off him, then ripped his undertunic until it hung in tatters and he was left wearing nothing but his loincloth. When one of them reached for the fascinum Titus tried to fight back, but he felt like a child flailing at giants. The Praetorian with perfect teeth struck him hard across the face, jarring his teeth and leaving him dazed and unsteady and with the taste of blood in his mouth.

They grabbed him by the arms, pulled him out of the little room, and began taking him somewhere else. In the open space behind the stands, they passed two men in senatorial togas. Titus tried to raise his arms, but the Praetorians restrained him.

“Help me!” he shouted.

The senators glanced at him. One of them muttered, “Filthy arsonist!”

The Praetorians struck Titus across the face to silence him and shoved him to a gate. The gate opened and Titus was forced into a dimly lit enclosure. Above him he could hear the murmur of the crowd. All around him echoed the creaking of the wooden stands as people moved about overhead. As his eyes adjusted to the darkness, he saw that the cell was quite large and full of people, most of them in rags or wearing little more than he was. They were filthy and unkempt and stank of urine and sweat. He passed among them, staring at their faces. Some were trembling with fear and muttering prayers with their eyes tightly shut. Others were oddly calm, speaking to their companions in low, reassuring voices.

“In such a wicked world, death is a release to be longed for,” said a man with a long white beard. Titus had seen him once in Kaeso’s rooms. “Even a death under circumstances as horrible as this is better than life in such a world. Death will deliver us to a better place.”

A harried stage manager scurried by, followed by a group of Praetorians. “I am trying to maintain order here; I am trying to keep to the emperor’s schedule of events!” the man shouted. “Now, I need you fellows to divide the prisoners into groups-”

Titus ran toward the man. “Listen to me!” he said. “A mistake has been made. I shouldn’t be here-”

The man started back, as if a wild dog had jumped at him. Before Titus could say another word, one of the Praetorians raised a shield and used it to shove him back. By a flicker of torchlight Titus caught a glimpse of his reflection in the highly polished metal. He was shocked at what he saw.
