They returned to the hills overlooking the Tiber, the site where they had been exposed as infants. They could not agree on which hill should house the new city. When an omen to resolve the controversy failed to provide a clear indication, the conflict escalated and Romulus or one of his followers killed Remus. In a variant of the legend, the augurs favoured Romulus, who proceeded to plough a square furrow around the Palatine Hill to demarcate the walls of the future city. When Remus derisively leapt over the "walls" to show how inadequate they were against invaders, Romulus struck him down in anger. In another variant, Remus died during a melée, along with Faustulus.
