in *Antiquity*, an officer in the Roman army, who had the command of two thousand men. The emperors had also ducenarii among their procurators or intendants, called *procuratores ducenarii*. Some say that Ducenarii were those whose salary was two hundred sesterces; as in the games of the circus, horses hired for two hundred sesterces were called *ducenarii*. Others hold that ducenarii were those who levied the two hundredth penny, or the officers appointed to inspect the raising of that tribute. In the inscriptions at Palmyra, the word *ducenarius*, in Greek *δοκεναριος*, occurs very frequently.
