From 365 onwards Rome kept 4 aediles (2 plebeian and 2 curule), who superintended different parts of the city. The honors of the curule aediles were: the honorary chair known as a sella curialis, the toga praetexta, precedence in speaking in the senate, and the right of the nobility to have a wax mask in their likeness. Curule aediles could also announce edicts related to trade. Like a plebeian aedile, the person of the curule aedile was sacrosanct.
The curule aediles had responsibility for the ludi Romani and the Megalenses, which could be very expensive.
