«Regulae iuris» e metodi della «scientia iuris». Prospettive di approfondimenti

The topic of regulae iuris has been treated several times, also recently. Nevertheless, the results are not satisfactory yet and mainly concern the iurisprudentia of the late respublica and principatus which gave birth even to a true literary genre. The study draws the attention on the age of late antiquity and the compilation of Justinian. In the first one the regulae iuris were no longer considered as a synthesis of the existing regulations or of dialectical arguments, but as actual regulations. On the contrary, Justinian / Tribonian, despite having given legal force to the material taken from the works of ancient jurists, downgraded the definitiones and regulae considering them imprecise by nature and useful only if corresponding to the existing law.
