»Cicero's Topica and his Program >de iure civili in artem redigendo<«: Methodology and topics are booming in legal history and classical studies. Nevertheless, there is no overall analysis of Cicero's Topica, which combine law and rhetoric, topics and dialectic, systems thinking and individual case argumentation. The volume fills this gap with results of interdisciplinary research: as part of the program De iure civili in artem redigendo, the Topica offer a legal methodology, which, however, has not been received by the Roman jurists, who were more focused on interpretation and comparison of cases.
