Nero Claudius

Nero Claudius Caesar Augustus Germanicus, the Fifth Roman Emperor, had the reputation of a notorious tyrant whose rule was made up of schemes and poison as she oppressed all religious forces, especially Christians, and the Roman Senate during the period from 50 to 60 AD. She was regarded in the same light as the devil, for the assumed Hebrew pronunciation of her name as emperor, Nero Caesar pronounced as "NRVN QSR", equates with the "Number of the Beast".
