The Answer is Answer would ideally include the following. Diocletian insisted on the title
dominus ("master" or "lord") rather than princeps (meaning "first man" among social equals). Historians now refer to this period of Roman rule as the dominate. To this title he added spectacle, public works, and court ceremony. The dominus began receiving people while seated on an elevated platform, dressed in jeweled robes, and wearing on his head a diadem, the jeweled band associated with the old monarchy. To illustrate the dominus's distance from other men, a series of veils separated the waiting room from the audience room. All of these practices were designed to emphasize Diocletian's superiority to and separation from those he ruled over.
