Hadrian, famous for his long and extensive travels throughout the empire, realized that he needed a reliable representative in Rome while he was away. Therefore, in 125, Hadrian elevated Turbo to the position of Praetorian prefect, that is commander of the Praetorian Guard. He held this title until 134. It is at this point that no more records are found of him. It seems possible that Turbo, along with many others, fell out of favor with Hadrian later in his reign; however, it is also possible that Turbo died from natural causes.
