The grandsons of Numitor could no longer live as shepherds on Mount Palatine, which they had learned to love. Nor could they dwell quietly in Alba, for all their lives they had been used to live free among the mountains, nor had they been subject to any king.
So the princes made up their minds to leave Alba, and to build a city for themselves on the hills they loved.
But the brothers could not agree on which hill to build their city, Romulus choosing the Palatine, Remus the Aventine.
Not knowing how to settle their dispute, they asked Numitor to help them. He bade them, as the custom was, to appeal to augury—that is, to watch for a sign or omen from the gods. These signs were given in many different forms, sometimes by the flight of birds, as happened now.
The princes determined to follow their grandfather's advice. Romulus went to Mount Palatine, Remus to Mount Aventine, and patient through one long day they watched for a sign.
But no sign appeared. The slow hours passed, and night drew on apace, yet still the brothers never stirred.
Then, as darkness faded before the dawn, Remus saw, far off, dark, moving shapes. Were the gods going to be gracious, the prince wondered, and after so many hours send a sign?
Nearer and nearer drew the dark shapes.
"Ah!" Remus cried sharply, "it is a good omen." For now he could see that the moving forms were six vultures winging their way toward the west. These birds were sacred to the gods, and did no harm to corn, fruit, or cattle, nor would they, indeed, wound any living thing.
Swiftly Remus bade a messenger to go tell his brother of the good omen vouchsafed to him. But even as his messenger sped to do his will, Remus was crestfallen. For before him stood one of the servants of Romulus to tell him that his brother, too, had seen a flight of vultures, but while Remus had seen six birds, Romulus had seen twelve.
What was to be done? It seemed now that the brothers were not thinking on which hill the city should stand, but of which of them should build the city. Remus believed that the augury proclaimed him as the founder of the new city. Romulus was sure that it was he who was intended by the gods to build it; for had not he seen twelve vultures while his brother had seen but six?
The princes turned to their followers, demanding who should be their king. Then loud and lusty was the answering shout: "Romulus, Romulus, he shall be our king!"
