This paper shows how the republican model of Cicero has been transmitted fragmentarily, through the Italian civic humanist tra-dition (Maquiavelo), the English republican humanism of XVI, XVII and XVIII centuries, and the republicanism of the American patriots, (“neo-republicanism”). The proposals of Pettit and Brug-ger are analyzed, and a great variety of positions that some con-sider “republican” are summarily reckoned. Finally, it is main-tained that the classic republican model is present in a very frag-mented way in contemporary political theories, for these theories are incapable to accept some strong anthropological, ethical and metaphysical theses. Cicero’s model of republicanism appears to us like in a large scale copy or replica, precisely in the political and legal reality of the contemporary world, in its practices and institutions, and in the political function of its theoretical reflec-tions.
