The magistrateship is a well-documented form of Etruscan government, especially in the fifth to third century BC. A number of titles for such officials are recorded in inscriptions, most prominently Zilath, but also other terms such as camthi, macstrev, and maru (possibly treasurer). Various extra designations, specifying precise roles, were added to this general office, but the precise meaning cannot be established. A good body of inscriptional evidence derives from Tarquinia and its probably dependent cities of Tuscania, Musarna, and Norchia. The main city of Tarquinia has the greatest range of magistrate titles.
