The triumph concluded without incident. The prisoners (except young Juba) were duly executed, and a sacrifice was offered in gratitude to Jupiter atop the Capitoline. Then, without a pause, attended by a vast retinue of officer, senators, and priests, Caesar began to make his way down the Capitoline, heading for the new Temple of Venus.

After the triumph, my family and I remained in the stands for a while, waiting for the crowd to thin. As we began to descend, I saw a now-familiar figure mounting the steps, heading toward us. It was Calpurnia's messenger. The look on his face was grim. He was too out of breath to speak. Without a word, he extended a tablet toward me. I took it from him, undid the ties, and opened it.

The letters had been so crudely scratched in the wax-as if in haste or great agitation-that for a moment I could make no sense of them. Then, all at once, the words jumped out at me:

Porsenna is dead. Come to me at once. The messenger will bring you.

I lowered the tablet. Bethesda was staring at me. "From her?" she said.

"Yes. I must go with this fellow."

"Take Rupa with you."

"Of course. And you and the family?"

"We shall attend the dedication of the temple, as we planned. In the standing area, I presume." While Caesar had arranged for us to have seats in the stands for his triumphs, he had not followed up with any such arrangement for the dedication. I had tried to explain to Bethesda that the seating for the ceremony was strictly limited, but she was not happy.

"If you hurry," I said, "perhaps you can still find a good spot, not too far back."

Diana drew close to me. "What does Calpurnia say? Is there some sort of trouble?"

"The haruspex is dead. Murdered, I presume."

"I should come with you, Papa."

"I think not. The woman is quite particular about whom she'll allow into her presence."

"But Rupa is going with you."

"Rupa is my bodyguard."

"If I were your son instead of your daughter, you'd take me along without question."

Whether this was true or not, I was no mood to argue, and the messenger was growing impatient. He deftly took the tablet from my hand, rubbed out the letters, and pulled at my toga.

"We should hurry, please!" he said.

"Davus, look after Diana," I said, fearful that she would try to follow against my orders. "Rupa, come with me."

We followed the man down the steps and into the crowd.

I had assumed that the messenger would lead me to the house of Calpurnia, but he turned in the opposite direction.

"Where are you taking us?" I said, suddenly suspicious.

"To the mistress, of course." He gripped my toga again. I knocked his hand away.

"This isn't the way to the Palatine."

"The Palatine?"

"Where she lives."

"She's not at home. She at the Temple of Venus. Please, hurry!"

Of course, I thought; the dictator's wife would have to attend the dedication, no matter what had happened to her haruspex. I followed quickly, realizing Diana and the family could have come at least partway with me, after all. But it was too late for them to rejoin me. We were separated by the crowd.

The open square before the temple was already thronged with people, and more were arriving from all directions. The standing area looked uncomfortably crowded-I had to wonder where Diana and the family would find space-but the benches nearer the temple were not yet filled; dignitaries are often the last to arrive. Some sat, while others milled about and conversed with their neighbors. The atmosphere was much like that at the theater before the crier announces that the play will begin.

In front of the seating area, at the foot of the temple steps, a large space was being kept clear by a row of lictors. Here, a marble altar had been erected for the ritual sacrifice. Close by the altar, a long ceremonial tent had been set up. Within the tent, those participating in the dedication could gather and prepare, unseen by the crowd.

The messenger led me toward the tent. The lictor at the entrance refused to let Rupa come inside. It seemed pointless to argue. The area within that tent was probably the safest, most secure place in all Rome.

I stepped from harsh sunlight into the diffused, warm glow of the tent. I smelled incense and flowers. As my eyes adjusted, the first thing I saw was the ox intended for sacrifice. It was a magnificent white beast, its horns garlanded with flowers and laurel leaves. It was circled by the young camilli holding shallow libation bowls to receive the spilled blood and the severed organs that would be offered to the goddess. Some of the boys and girls were washing the flanks of the ox with woolen cloths that had been dipped in warm, jasmine-scented water, while others were daubing the animal's hooves with cinnabar to stain them red. The ox stood quite still, its heavy-lidded eyes gazing straight ahead, seeming to bask in their attentions.

As my eyes continued to adjust, I saw others in the tent. Most were priests and lictors, but there were a few senators and other men in togas as well. Arcesilaus was also there, wearing a tunic covered with dust and spotted with paint. The large placard displaying the new calendar had been placed on a stand where it could be worked on, and he appeared to be making last-minute alterations with a set of paints, while another man-not a Roman, to judge by his Egyptian jewelry and pleated linen gown-looked on.

The artist glanced over his shoulder, saw me, and scowled. "You!" he said.

His perfunctory salutation canceled any need for pleasantries.

"Let me guess," I said. "The calendar contains an error, and this fellow is one of Cleopatra's astronomers from Alexandria, advising you on the necessary correction."

"And with plenty of time to spare!" said Arcesilaus sarcastically. "The fellow never showed up yesterday. Only now am I being told that the extra day in Februarius during a leap year is added six days before the Kalends of Martius, not eight. Ridiculous! So now, after all my painstaking effort, this little presentation will look as slapdash as if I'd turned it out on the spur of the moment. Caesar isn't paying me enough to endure this torment!"

His voice rose to a yell. He began to quake, vibrating like a plucked string, and raised his fists in the air, the veins in his biceps bulging like the vein in his forehead. The Alexandrian started back in fear, but Arcesilaus's attention was wholly on the placard. He looked as if he intended to beat it with his fists, and it was easy to imagine the delicate thing being totally demolished in a matter of heartbeats.

He was restrained by a hand on one shoulder.

"Don't do it, artist!" said Calpurnia. "Don't even think of it!" There was a shrill edge to her voice that made me shiver. Even the hot-blooded Arcesilaus was chilled by it. The vein pulsing across his forehead vanished, like a snake disappearing into the earth. Muttering, he turned back to the placard and resumed his work.

Before I could speak, Calpurnia gripped my arm and led me to a spot away from the others.

"My slave gave you the message?"

"Yes. Porsenna is dead?"

"Murdered! Stabbed, just like Hieronymus."

"When and how?"

"My messenger found Porsenna's body in his house on the Aventine less than an hour ago. Porsenna was to join me before the end of the triumph, so that we could come to the temple together-"

"You planned to appear with Porsenna in public, where Caesar might see the two of you together? I thought it was your wish that Caesar should never know you were consulting a haruspex."

"I don't care any longer what Caesar knows or doesn't know. The danger is too great-and this proves it! Yesterday, Porsenna was more certain than ever of the menace to Caesar. He told me that today would be the day of greatest danger, and the place of greatest danger would be here, at the dedication of the temple. And now, Porsenna is dead!"
