I'm a little torn on how to review Donald Kagan's "Thucydides: The Reinvention of History." I am not a professional historian but majored in ancient history in college, and my favorite professor and thesis advisor studied under Professor Kagan at Yale (and was such a fan he changed his major from math to Greek History!). Professor Kagan is among the most respected historians of the ancient world who ever taught, and so any criticism of his work from me seems more than a bit presumptuous.
But I read his book, and Goodreads gives me the opportunity to do this, so here we go.
In a nutshell, this book by Kagan is a great heaping bowl of fresh spinach seasoned only by a pinch of salt and pepper. Kagan is a writer without flourish or demonstrable style - he is pure mental nutrition. Fresh unseasoned spinach is has a nice flavor, but its primary benefit is its colossal nutritional content. If you read this offering by Kagan, you'll be much better informed by the end, but you may not enjoy the journey all that much.
Kagan offers a thorough description of what we know about the Athenian general and writer Thucydides, and how his unusual circumstances (a once-favored general who is exiled by the Athenians for perceived failures) led him to take the highly unusual step of writing in great detail about the Peloponnesian War (the name for the conflict that ultimately saw the Spartans defeat the Athenians in the 5th century BC) so that readers for all time would know exactly why and how it was fought. Thucydides appears to have remained pro-Athenian in a macro sense but also somewhat resentful of his exile by the Athenian mob (which is understandable). And Thucydides also appears to have taken the unusual step of trying to understand the Spartan perspective as well.
In Kagan's telling, Thucydides made an admirable attempt to seem 'objective' (which was revolutionary in and of itself) but he also was a revisionist historian, countering what he saw as improper contemporary accounts of the war. Kagan, with his encyclopedic understanding of all the relevant source material, efficiently mines other sources, such as contemporary plays, to call into question some of Thucydides' assertions or to put them in a larger context. (Being an ancient historian is kind of like being an astronomer - you're constantly extrapolating from limited information - Kagan is a master.) Kagan susses out Thucydides' biases, such as being very pro-Pericles and against "true democracy," which Thucydides would see as too close to "rule by the mob." Rather, as an aristocrat and as someone who felt the stinging rebuke of an ill-informed Athenian populace, Thucydides was in favor of a democracy under the influence of wise stewards such as Pericles.
All this is entertaining for someone who is very familiar with the Peloponnesian War - if you're looking for a one-volume history of that war, this is not the book you're looking for (Kagan wrote the books you *are* looking for - rest assured!). In fact, it has been so long since I've done any reading about this war I wish I had done some other reading first before diving into Kagan's book.
Overall, I'm recommending the book but I give it three stars because it has a very limited target audience. Also, the subtitle ("the reinvention of history") is rather grandiose. Kagan's ultimate conclusion - that even though Thucydides claimed to write a history for all time, but we need to understand his biases and philosophy in order to truly understand his history - is not all that illuminating - we need to understand those for any writer.
But if you're a hard-core fan of the history of the ancient world, this book is for you.
