Res Gestae

In the maintenance of the soldiers he was exceedingly careful; somewhat critical at times in evaluating services, he bestowed appointments at court by the plumb-line,[*](The metaphorical use of this expression does not seem to be common; it occurs also in Ausonius, Parentalia, v. 8, ad perpendiculum se suosque habuit. ) as it were. Under him no one who was to hold a high position was appointed to a post in the palace suddenly or untried, but a man who after ten years was to be marshal of the court, or head treasurer, or to fill any similar post, was thoroughly known. It very rarely happened that any military officer passed to a civil magistracy, and on the other hand, none were put in command of soldiers who had not grown hardy in the dust of

battle.
