Abstract
Histories 1.40 is designed to set the scene for Galba's assassination. It begins by bringing the emperor into the crowded Forum, but then it switches to Otho and his followers, dwelling on the horror, not of the act they plan, but of their readiness to commit it. The text is not problematical, but since the point behind the first two sentences is not entirely clear, this has prompted occasional emendation, repeated discussion, and continuing perplexity. The difficulty arises, in good measure, from the assumption that Tacitus is saying much the same as Plutarch. As has been remarked more than once, the two authors no doubt drew their material from the common source, but they have in mind different time-frames and different viewpoints. Nor does this end the matter. A skewed perspective on these sentences has also led one scholar to dissect the chapter in a manner purporting to show that Galba's fate, not the Othonians' willingness to bring it about, is Tacitus' main concern.
