What is the author's style in The Agricola; and the Germania; by Cornelius Tacitus?

As a historian, Tacitus cares little for geography or military history, and often interjects personal opinion as fact. This is seen clearly in his account of people of Germania. While his descriptions are detailed, there is little support for many of his claims, and he does not pretend to give credibility to his facts, but instead seems to assume the reader either knows such support, or assumes him to be credible. While parts of his descriptions are well known facts, there are other areas, such as his opinions of tribes run by women, that are clearly opinions he presents as facts. The overall impression left is that of a combination of fact and legend that serves primarily to glorify the German people.
