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 )
