Marcus Aurelius (121-180 AD), emperor of the ancient Roman Empire. During his reign, the Roman Empire was turbulent and crisis-ridden, so he spent almost his life on horseback or in a chariot. Although people still shouted "Long live the Emperor" wherever he went, he himself knew that his days were numbered and was ready to give up his life at any time. Although he shoulders the heavy responsibility of governing the country, he still pursues diligently, relentlessly explores the unknown world, thinks about the universe and other philosophical issues, and aspires to become a saint, a philosopher like Socrates. Therefore, Aurelius is worthy of being called the "Emperor Philosopher" and belongs to the Stoic school. "Meditations" is his philosophical thinking about the universe, nature, gods, and life. Many chapters in the book were written on the journey of swords and swords, so it is also called "Meditations on Horseback".
