Agricola rendered an account of his victory to the emperor, in terms remarkable for their modesty and simplicity. The jealous Domitian received his letter with apparent joy, but secret wrath: with his usual cunning, however, he dissembled his real sentiments till time had weakened the enthusiasm of the people and the favour of the army for the man he hated. Gradually a report gained ground that the victorious general was to be recalled from the scene of his triumphs, to take the command in Syria, and Domitian demanded for him the honours of a triumph. The victor dared not, however, present himself to the acclamations of the people, for fear of exciting the jealousy of his imperial master. He entered Rome privately, and by night, and presented himself before the tyrant, who received him coldly and in silence. He soon became confounded with the crowd of courtiers, and only escaped from the peril of his glory by appearing himself to forget it. Little is known of the state of Britain from Domitian to Hadrian, when many of the nations who had been subject to the yoke of Rome began to show signs of impatience, and all the cares of the new emperor were to confirm the peace of the world. He re-established the system of Augustus, abandoned the conquests of Trajan, and limited the empire in the east to the Euphrates. He visited the provinces, and arrived at last in Britain, where he corrected many abuses, and built, in order to repress the incursions of the Caledonians, the celebrated wall (a description of which will be found in the following chapter) which bore his name. It extended upwards of eighty miles, from the north of the Tyne to the Solway (A.D. 120). Rome thus abandoned without a struggle the country included between the wall of Hadrian and that of Agricola, an extent of about 100 miles; a portion of it, however, was regained under Antoninus Pius, the adopted son and successor of Hadrian, in 139, when a rampart was constructed between the Forth and the Clyde; it was subsequently strengthened by the Emperor Severus, in 208, and hence is generally called by his name.
