MASTER (magister), was a title frequent among the Romans: they had their master of the people, magister populi, who was the dictator. Master of the cavalry, magister equitum, who held the second post in an army after the dictator. Under the later emperors there were also masters of the infantry, magistri peditum. A master of the census, magister census, who had nothing of the charge of a censor, or subcensor, as the name seems to intimate; but was the same with the praepositus frumentariorum.
