Evelyn Shirley Shuckburgh, Augustus. The life and times of the founder of the Roman Empire… (1903)
“ After the restoration of the standards and prisoners from the Parthians in B.C. 20, and when the peaceful settlement of the Eastern provinces and subordinate kingdoms had been carried through or fairly started, Augustus appears to have thought that the greater part of his life's work had been accomplished. The frontiers of the Empire had been settled and secured. The Eastern provinces had been visited, necessary reforms introduced, and great works of public utility set on foot. ”
