The name that is transliterated as “Augustus” in English means “venerable,” “sacred,” “kingly.” (Source: Cornwall / Smith 1997 )
In Libras (Brazilian Sign Language) it is translated with a sign that combines “C” (for Caesar, the title of the powerful ruler of Rome) and “adopted” since he was adopted by Julius Caesar (Source: Missão Kophós )
