This essay examines the nature and role of mythical histories in English medieval towns. Myths concerning the origins and special destinies of particular cities were widespread and long-lasting. For contemporaries they acquired meaning through their interaction with changing historical circumstances. Evidence for their circulation in both elite and popular domains is reviewed. Their significance was not unambiguous; they were, rather, contested territory, a means through which townspeople articulated their particular views about the nature and purpose of urban society. Their effect, therefore, could be to assist both in the formation and in the transformation of that society. Issue is taken with the argument that the early modern period saw a weakening of the potential force of such myths.
