Plutarch: Moralia

The Moralia (Ancient Greek: Ἠθικά Ethika;  loosely translated as "Morals" or "Matters relating to customs and  mores") is a group of manuscripts dating from the 10th-13th centuries,  traditionally ascribed to the 1st-century Greek scholar Plutarch of Chaeronea.[1] The eclectic collection contains 78 essays and transcribed speeches. They provide insights into Roman and Greek life, but often are also timeless observations in their own right. Many  generations of Europeans have read or imitated them, including Michel de Montaigne and the Renaissance Humanists and Enlightenment philosophers.
