13. But although Cerealis had diminished the care and fame of his successor, the burden was sustained by Julius Frontinus, a man of high courage. Overcoming at once the spirit of the enemy and the difficulties of the country, he subjugated the warlike and powerful nation of the Silures.
14. To him succeeded Agricola, who not only maintained the peace of the province; but for seven years carried on war against the Caledonians and their warlike king Galgacus. He thus added to the Roman empire nations hitherto unknown.
15. But Domitian, envying the superior glory of Agricola, recalled him, and sent his lieutenant Lucullus into Britain, because he had suffered lances of a new form to be named Luculleas after him.
16. His successor was Trebellius, under whom the two provinces, namely, Vespasiana and Mæata, were wrested from the Roman government; for the Romans gave themselves up to luxury.
17. About this time the emperor Hadrian visiting this island, erected a wall justly wonderful, and left Julius Severus his deputy in Britain.
18. From this time nothing worthy of attention is related, until Antoninus Pius carried on so many wars by his generals.

19. Pius dying, Aurelius Antoninus gained many victories over the Britons and Germans.
20. On the death of Antoninus, when the Romans deemed their acquisitions insufficient, they suffered a great defeat under Marcellus.
21. To him succeeded Pertinax, who conducted himself as an able general.
22. The next was Clodius Albinus, who contended with Severus for the sceptre and purple.
