Letters 108.31

The philologist also notes that the officer whom we call dictator, and about whom we read in our histories under that title, was named in old times the magister populi; such is the name existing to-day in the augural records, proved by the fact that he whom the dictator chose as second in command was called magister equitum. He will remark, too, that Romulus met his end during an eclipse; that there was an appeal to the people even from the kings (this is so stated in the pontiffs’ register and is the opinion of others, including Fenestella).
