Plutarch (/ˈpluːtɑrk/; Greek: Πλούταρχος, Ploútarkhos, Koine Greek: [plǔːtarkʰos]; later named, upon becoming a Roman citizen, Lucius Mestrius Plutarchus (Λούκιος Μέστριος Πλούταρχος); c. AD 46 – AD 120) was a Greek historian, biographer and essayist, known primarily for his Parallel Lives and Moralia. He is considered today to be a Middle Platonist. Plutarch's surviving works seem to have all been originally written in Koine Greek.
