"I had remarked a certain Antoninus"

Titus Fulvius Aelius Hadrianus Antoninus Pius (86-161 AD) was adopted by Hadrian after the death of Lucius Aelius, and became his immediate successor. He was a nobleman whose family came from Nimes, and had followed the usual route to power, serving as Consul in 120, and subsequently as Proconsul in Italy and Asia. During his reign, the borders of the Empire were extended to a limited extent, both eastwards into Germany and northwards into Scotland. Unlike Trajan and Hadrian, however, he never left Italy during the course of his reign.
