Xenophon’s account, written many years after the events recounted, is not a bare retelling of facts. We cannot know how much of the tale is embellished, and how much is literal. The general outlines are likely to be true. Precise details, such as the precise language of the speeches, must have been rendered, at best “more or less” as Xenophon recalled. So, we can read the book as a record of actual events, with some caveats for the passage of time and biases of the author.
However, it is also the case that there is a symbolic element in the book, in which Xenophon is using the narrative to illuminate some “big picture” issues. To do that, he uses some artistic devices, woven into the narrative. One of these, which I mentioned in my previous post is the mixing of the literal and metaphorical “ascent” and “descent” of the army, and of Xenophon himself.
