“Hail, Emperor!” As one they roared out toward the Imperial box. “We salute you from death’s shadow!”

The clank of sharpened weapons. The scrape of plated armor. The crunch of many feet on sand as they spread out in their pairs. A few mock combats first with wooden weapons, and then the Emperor dropped his hand.

The blades crashed. The audience surged forward, straining against the marble barriers, shouting encouragement to the favorites, cursing the clumsy. Waving, wagering, shrieking.

Don’t look. Swish, swish, went the fan. Don’t look.

“Thea,” Lepida said sweetly. “What do you think of that German?”

I looked. “Unlucky,” I said as the man died howling on his opponent’s trident. In the next box, a senator threw down a handful of coins in disgust.

The arena was a raging sea of fighters. Already the sand was patched with blood.

“The Gaul over there wants mercy.” Pollio peered out, sipping at his wine cup. “Poor show, he dropped his shield. Iugula!”

Iugula—“Kill him.” There was also Mitte—“spare him”—but you didn’t hear that nearly so often. As I was to find out, it took an extraordinary show of courage to move the Colosseum to mercy. They wanted heroism, they wanted blood, they wanted death. Not scared men. Not mercy.

It was over quite quickly. The victors strutted before the Imperial box, where the Emperor tossed coins to those who had fought well. The losers lay crumpled and silent on the sand, waiting to be raked away by the arena attendants. One or two men still writhed in their death throes, shrieking as they tried to stuff the guts back into their own bellies. Laughing tribunes and giggling girls laid bets on how long it would take them to die.

Swish, swish, swish. My arms ached.

“Fruit, Dominus?” A slave came to Pollio’s elbow with a tray of grapes and figs. Lepida gestured for more wine, and all through the patrician boxes I saw people sitting back to chatter. In the tiers above, plebs fanned themselves and looked for the hawkers who darted with bread and beer for sale. In his Imperial box the Emperor leaned back on one elbow, rolling dice with his guards. The morning had flown. For some, dragged.

For the midday break, business was attended to inside the arena. The dead gladiators had all been carted away, the patches of blood raked over, and now the arena guards led out a shuffling line of shackled figures. Slaves, criminals, prisoners; all sentenced for execution.

“Father, can’t I have more wine? It’s a special occasion!”
