I enjoyed Vol. 7 of Plutarch's "Moralia," as the title is translated in English, so much that I'm set to eventually read all the 32 volumes. Volume 7 has three works: The Bravery of Women, Similar stories that exist in the Greek and the Roman histories (this title I paraphrased it from the Greek. I'm not sure how exactly is titled in English translation), and my very favorite work of the three: The Fortune of the Romans.
I loved all 3 works, but this last work, The Fortune of the Romans, was really great! Here Plutarch uses personification to bring against each other the Fortune and the Virtue, and they discuss whether the Roman's success was due to having good fortune, good luck as we would say today, or due to their virtue. Interesting and thought provoking this argument is discussed through specific examples of certain Roman's lives or deaths.
