ARCHIGUBERNATA, or ARCHIGUBERNITES, in Antiquity, the commander of the imperial ship, or that which the emperor was aboard of. Some have confounded the office of archigubernus with that of prefectus classis, or admiral; but the former was under the command of the latter. Potter takes the proper office of the archigubernites to have been, to manage the marine affairs, to provide commodious harbours, and order all things relating to the sailing of the fleet except what related to war.
