This is an account of the foundation legend of Rome, how the twins Remus and Romulus were miraculously suckled by a she-wolf, and how Romulus founded Rome and Remus was killed at the moment of the foundation. What does the story mean? Why have a twin, if he has to be killed off? This is the first historical analysis of the origins and development of the myth, and it offers important insights into the nature of pre-imperial Rome and the ways in which myths could be created and elaborated in a nonliterate society.
