After years of searching archaeologists believe they have now located the wolf's lair, the nursery in which Romulus and Remus, the legendary founders of Rome, were raised. These twin sons of Mars, the war god, fell out when Remus mocked the city walls that Romulus was building. Romulus killed his brother and became the first king of Rome. Interestingly, the last emperor of Rome (of the Western Empire), was also called Romulus.
