“Ah, but if that happens, you say, there will be a wall to keep us safe. What nonsense! Did the twins learn nothing from their victory over Amulius? Did walls keep Amulius safe? Did his mercenary warriors save him? Did all his treasure buy him even a single breath when Romulus cut his throat?”
Potitius shook his head. “All you say would make perfect sense, Father, except for one great difference between Amulius and the twins. Amulius lost the favor of the gods; fortune turned against him. But the gods love Romulus and Remus.”
“You mean to say that you love them, my son!”
“No, father. I speak not as their friend, but as a priest and a haruspex. The gods love the twins. It is a manifest fact. In every battle, especially a battle to the death, there must be a winner and a loser. Romulus and Remus always win. That could not happen unless the gods willed it to be so. You speak with scorn of the path they’ve chosen, but I tell you that their path is blessed by the gods. How else can you account for their success? That is why I follow them, and why I use all the skills I possess to shed light on the way ahead of them.”
His father, unable to refute these words, fell silent.
The twins agreed that a wall should be built, but they did not agree about its location.
Romulus favored a wall that would encircle the Palatine. Remus thought the wall should be built around the Aventine, further south. Day after day, Potitius listened to them argue.
“Your reasons are purely sentimental, brother” said Remus. “We were raised here on the Palatine, therefore you wish to make it the center of Roma. But no one lives on the Palatine except a few herders and their livestock. Why build a wall around a city of sheep? Or do you intend to drive away the herders and cover the Palatine with buildings? I say, leave this hill wild and open, as it was when we were boys, and build up the city elsewhere. South of the Spinon is the natural place to expand, close to the riverfront. The marketplace, the salt bins, and the slaughtering yards are already pushing against the foot of the Aventine. That is the hill we should encircle with a wall, upon which we should begin to build a proper city.”
“How perfectly reasonable you sound, brother!” Romulus laughed. The two brothers, along with Potitius and Pinarius, were strolling across the Palatine. The sky was dazzling blue with white clouds heaped against the horizon. The hill was covered with green grass and spangled with spring flowers, but there was not a single grazing sheep to be seen; the sheep had all been gathered into their pens, which were adorned with juniper boughs and wreaths of laurel leaves. This was the day of the Palilia, the festival of the goddess Pales. Here and there, streamers of smoke trailed into the sky. Each family had set up its own altar to Pales, and upon these raised stones they were burning various substances: for purification, handfuls of sulfur, which emitted sky-blue smoke, followed by twigs of fragrant rosemary, laurel, and Sabine juniper, then an offering compounded of beanstalks mixed with the ashes of calves already burned, sprinkled with horse blood. With juniper branches, the shepherds wafted the smoke across the penned animals; the sacred smoke of Pales would keep the herd healthy and fertile. Afterward, the shepherds would feast on millet cakes and drink bowls of warm milk sprinkled with purple must.
“Perfectly reasonable,” Romulus said again. “But this is not about reason, brother. It’s about creating a city fit for two kings. You say I favor the Palatine because I’m sentimental. Indeed, I am! How can you walk across this hill on the day of the Palilia and not feel the specialness of this place? There was a reason the gods left our cradle on the slope of the Palatine. Truly, this is the very heart of Roma! It’s around the Palatine that we must build a wall, to honor the home that nurtured us. The gods will bless our enterprise.”
“Ridiculous!” snapped Remus, with a harshness that startled them all. “If you can’t listen to reason, how do you expect to rule a city?”
Romulus strained to keep an even tone. “I’ve done a good enough job so far, brother, building an army and leading them in battle.”
“Running a city will be a different matter. Are you such a fool you can’t see that?”
“You dare to call me a fool, Remus? I wasn’t the fool who got himself captured by Amulius and needed rescuing—”
“How dare you throw that in my face! Or do you enjoy reminding me of the hours I spent suffering, needlessly, because you wasted time here in Roma—”
“Unfair, brother! Untrue!”
“And because you strangled Amulius, you wear the crown every day, even though you promised it would be shared equally between us.”
“Is that what this is about? Take it! Wear it!” Romulus lifted the iron crown from his head, cast it to the ground, and stalked away. Pinarius ran after him.
When they were boys, the twins had never argued. Now they seemed to argue all the time, and their arguments grew more and more heated. From childhood, Romulus had been the more headstrong and impulsive, and Remus had been the one to restrain his brother. But the torture he had received at the hands of Amulius had wrought changes in Remus. His body had never fully recovered; he still walked with a slight limp. More than that, his even temper had deserted him; he had become as quick to anger as his brother. Romulus had changed as well since Alba. He remained as high-spirited as before but was more disciplined and purposeful, and more self-assured and arrogant than ever.
At Alba, Remus had suffered the tortures of Amulius; Romulus had enjoyed the glow of triumph and the satisfaction of rescuing his brother. One had been a victim and the other a hero. This disparity had created a rift between them, small at first but constantly growing. Potitius knew that the argument he had just witnessed was not about the wall, but about something that had gone terribly wrong between the twins, which neither could put a name to or knew how to set right.
The castoff crown had landed at Potitius’s feet. He stooped to lift it from the grass, and was surprised at how heavy it was. He offered it to Remus, who took it but did not place it on his head.
“This matter of the wall must be settled once and for all,” said Remus quietly, staring at the crown. “What do you think, Potitius?” He saw the troubled look on his friend’s face and laughed ruefully. “No, I’m not asking you to take sides. I’m asking your advice as a haruspex. How might we settle this matter by consulting the will of the gods?”
As quick as a blink, a shadow passed over them. Potitius looked up to see a vulture high above. “I think I know a way,” he said.
The contest was held the next day. It was not Potitius who called it a contest, but the twins, for clearly, that was how they thought of it. To Potitius, it was a very solemn rite, calling upon all the wisdom he had learned in Tarquinia.
The rite was conducted simultaneously upon each of the contesting hills. Romulus stood at a high spot on the Palatine, looking north; beside him was Pinarius, in his role as a priest of Hercules. Remus, with Potitius, stood on the Aventine, looking south. At each site, an iron blade had been driven upright into the earth, so that by its shadow the exact moment of midday could be determined. A mark had been made in the ground a set distance from the blade, to mark by the blade’s moving shadow the passing of a precise measure of time. Within that span of time, each brother and his priest would watch the sky for vultures in flight. The priests would keep count of each vulture that was sighted by scraping a furrow in the dirt with a spear.
Why vultures? Potitius had explained his reasoning to the brothers: “The vulture is sacred to Hercules, who was always joyful at the sight of one. Among all creatures, it is the least harmful; it damages neither crops, nor fruit trees, nor cattle. It never kills or hurts any living thing, but preys only upon carrion, and even then it will not prey upon other birds; whereas eagles, hawks, and owls will attack and kill their own kind. Of all birds, it is the most rarely seen, and few men claim ever to have seen its young. Because of this, the Etruscans believe that vultures come from some other world. Therefore, let it be the sighting of vultures that determines the will of heaven in situating the city of Roma.”
