Laudator Temporis Acti

Historia Augusta, 1: Life of Hadrian 12.6 (tr. David Magie):

During this period and on many other occasions also, in many regions where the barbarians are held back not by rivers but by artificial barriers, Hadrian shut them off by means of high stakes planted deep in the ground and fastened together in the manner of a palisade.

per ea tempora et alias frequenter in plurimis locis, in quibus barbari non fluminibus sed limitibus dividuntur, stipitibus magnis in modum muralis saepis funditus iactis atque conexis barbaros separavit.

Id. 11.2:

And so, having reformed the army quite in the manner of a monarch, he set out for Britain, and there he corrected many abuses and was the first to construct a wall, eighty miles in length, which was to separate the barbarians from the Romans.

ergo conversis regio more militibus Britanniam petiit, in qua multa correxit murumque per octoginta milia passuum primus duxit, qui barbaros Romanosque divideret.
