Augustus (magnified, sanctified) Honorary Latin title given in 27 b.c.e. to Octavian, great nephew and adopted son of Julius Caesar. The title was not hereditary but was taken by succeeding emperors as bestowed by the senate. The title of Augustus was reserved exclusively for the emperor, but the corresponding feminine style of Augusta was assumed by great ladies of the imperial house. The title was used by Christian emperors of the Holy Roman Empire. The Greek translation of the title was Sebastos, holy.
