Marcus Aurelius was Emperor of Rome from 161 AD to his death in 180. During his reign a horrible plague struck Europe, a plague that bears his name. As I write this, a plague named Covid-19 has ravaged the planet, killing more people in America than died in all of the wars we've been in since Korea, with the death toll now rising every day, and shut down most of the world's economy, throwing millions of people out of work. This is his philosophy, edited for the modern English reader, and illustrated.
