In the Agricola … Tacitus amalgamates biography and historical monograph. But the success of the combination is questionable. He gives roughly two thirds of the work to Agricola's governorship of Britain, and treats the climax of Agricola's campaigns at length, providing direct speeches for the two leaders, almost as if he were experimenting with full-scale history. Such extensive development of a part, albeit an important part, unbalances the whole. Again, most of what he tells us about Agricola's personality is conventional and unrevealing.… Some contend that Tacitus exaggerated Agricola's achievements and wilfully misconstrued his relations with Domitian. We cannot be sure, but certainly many matters in the Agricola are unclear or, like the insinuation of poisoning against Domitian, ill substantiated. There is, however, a case for the defence. Tacitus probably found little else worth relating about Agricola except the governorship, and hence made the most of it. In thus concentrating on military and administrative achievements, he followed a hallowed Republican tradition.… A Roman aristocrat should possess and display virtus, above all in warfare: to this pattern Agricola conformed. Thus one old-fashioned attitude underlies a work somewhat novel in conception.
