Xenophon's pro-Spartan sympathies frequently show through in his writing (see Hellenika, for example), though he is not entirely uncritical. OnIn this treatise on the Spartan constitution, Xenophon started with:
(see also the section below on Anabasis) This multi-genre text is Xenophon's longest work and focuses on Cyrus the Great (although much of it is fiction) but it was intended neither as a history nor a biography but rather as a treatisethesis on the training of a ruler. Cyropaedia is
This is similarly problematic in terms of motive. Perhaps he felt that the march of 10,000 Greeks through the heart of the mighty Persian empire was too good a story not to tell, but there is almost certainly more to it than that. In Anabasis, the theme of Leaders and Followers is evident, as it was in Cyropaedia, and Xenophon's desire to make known his thoughts on what he personally saw as something very important may well have been an important (but not only) reason for writing both Anabasis and Cyropaedia.
OTHER WORKS
Hipparchicus, On Horsemanship and Hunting with Dogs
Hipparchicus, On Horsemanship and Hunting with Dogs can all be considered technical treatise. They are instructional, but that does not appear to be the only reason that Xenophon wrote them. Hipparchicus, for example, sees Xenophon once again dealing with leadership, while Hunting with Dogs
is a definite outlier in Xenophon’s corpus of smaller works and a difficult text. It is made up of three distinct parts: an elaborate, mythological preface; an extensive attack upon the sophists at the end; in between, a fairly straightforward practical section concerning hunting.
