Abstract:
Scholars who devoted their attention to Medieval political thinking have correctly typified Aegydius Romanu's doctrine as the purest model of the so-called Papal Theocracy or Hierocracy. It was precisely that theocratic character which left unadvertised its theoretical importance and, consequently, minimised the strength of the conceptual groundings of Aegydius's political theory on absolute power. The article is organised in two directions: in the first place, it reconstructs the argumentation that Aegydius used to get to the notion of casus imminens; in the second place, it points out (and stresses) the theoretical links that relate the casus imminens with the theory of the totality of power (plenitudo potestatis).
