 DATE: The Emperor Tiberius wife, Julia, puts in an appearance  complaining about Diana being considered "too good for Caligula" and  Tiberius mentions his "30 years with Julia". Actually, his wife,  Julia, the daughter of his predecessor, the Emperor Augustus, had  been permanently exiled by her father for lewd behavior long before  Tiberius even became Emperor. By the time "The Robe" opens, in the  last years of Tiberius reign, Julia had been dead and forgotten for  decades.
