Le forme della regalità nella Roma latino-sabina

The analysis of historical sources, onomastics data, and the festive calendar, shows that the most archaic Roman kingship was structured in the form of a diarchy between a lifelong king-priest and a temporary warrior-king: the latter ruled in the season of war, while in peacetime the city government was led in turn by the patres (interregnum). This diarchy could be the result of the influence, on Roman institutions, of the constitutional structures of the Greeks and of the Italic peoples, since among other Indo-European cultures, like Vedic India and the Celts, the pattern seems rather to be a triad — composed of a priest, a supreme king and a warrior king — surviving in Rome only at a theological level in the Pre-Capitoline triad Iuppiter Mars Quirinus. Given these premises, the subsequent Etruscan monarchy appears to be the result of the rising of the army commander to a tyrannical and lifelong power, and of the marginalization of the rex sacrorum, while the Republic seems a partial restoration of the oldest constitution.
