While other works of Xenophon's have taken me a week or even longer to get through, I finished this one in just a night, and it wasn't even the only thing that I read that evening. Agesilaus is a biography of the titular Spartan king, and unlike Xenophon's "biography" of Cyrus the Great, is thought to be fairly accurate historically, if very brief, and somewhat biased. Where a modern biographer often goes out of his or her way to find "dirt" on their subject, highlighting their shortcomings and failures no matter how respected and revered a figure they might be, or how significant of feats they might have accomplished, it has been more common in history to write biographies that are meant to praise a figure and elucidate the person's admirable traits, that others might follow suit. Xenophon certainly falls into the latter category, and his effusive praise for Agesilaus renders him as a veritable paragon of virtue, representative of every admirable characteristic and quite devoid of any flaws of blemishes.
Continuing on through the collected works of Xenophon, we next have Hellenica, which much like Herodotus's Histories is intended as a historical narrative. This time, it picks up the account in 411 BCE, and covers about fifty years, to 362 BCE, which is apparently the year of the Battle of Mantineia. Apparently, it picks up the narrative thread of the Peloponnesian War immediately where Thucydides' history abruptly ends (which is also on my reading list, and I only know this because the information was conveniently included in the front of my translation of Hellenica), and may have been written just for his friends as a sort of historical "vanity" publication. Like The Ten Thousand, this is covering a topic to which Xenophon was a contemporary, so it is considered an important primary source, and hopefully has a bit more historical veracity than his not-really biographical treatment of King Cyrus, who founded the Persian Empire.
I've actually read this part before, but decided to re-read it in light of my recent reading of Herodotus's Histories, which covered the period about a hundred years or so before the events in The Ten Thousand, and provided a lot of valuable context for understanding what was happening in Xenophon's story. Unlike Herodotus, Xenophon is not writing about history in The Ten Thousand; he is writing a semi-autobiographical account of what happened to him and his companions during a campaign as mercenaries in a decidedly short-lived Persian civil war. Like Caesar in his Commentaries, Xenophon refers to himself in the third person, and the result is perhaps the most story-like and modern-seeming of all the ancient works that I've been reading recently. In fact, Conn Iggulden wrote a historical fiction novella primarily based upon the events in The Ten Thousand, and it was a very interesting experience to read that having already read its primary source.
The Histories themselves are split up into nine books, which more or less focus on the Greco-Persian conflicts of that time period, with numerous digressions to talk about the history of Egypt, Babylon, or other places that come up.
Unlike many other history books, which look at grand, sweeping ideas and focus on facts, dates, statistics, and artifacts, Brook presents major portions of Chinese history through the lens of narratives, sort of like miniature biographies. Each chapter focuses on a different individual of whom we have a record and who can be used to explain and demonstrate the evolution of China in that time period. This format helps keep the book from falling into the trap of many other nonfiction works I have read recently, where the first 1/3rd to 1/2 of the book is interesting, and the remainder is repetitive.
