The Roman emperor Marcus Aurelius Antoninus (a.d. 121—180) embodied in his person that deeply cherished, ideal figure of antiquity, the philosopher-king. His Meditations are not only one of the most important expressions of the Stoic philosophy of his time but also an enduringly inspiring guide to living a good and just life. Written in moments snatched from military campaigns and the rigors of politics, these ethical and spiritual reflections reveal a mind of exceptional clarity and originality, and a spirit attuned to both the particulars of human destiny and the vast patterns that underlie it. From the Hardcover edition.

Meditations (Medieval Greek: Τὰ εἰς ἑαυτόν, romanized: Ta eis he'auton, lit. 'things to one's self') is a series of personal writings by Marcus Aurelius, Roman Emperor from 161 to 180 AD, recording his private notes to himself and ideas on Stoic philosophy. Marcus Aurelius wrote the 12 books of the Meditations in Koine Greek as a source for his own guidance and self-improvement. It is possible that large portions of the work were written at Sirmium, where he spent much time planning military campaigns from 170 to 180. Some of it was written while he was positioned at Aquincum on campaign in Pannonia, because internal notes tell us that the first book was written when he was campaigning against the Quadi on the river Granova (modern-day Hron) and the second book was written at Carnuntum.

Marcus Aurelius Antoninus was Roman emperor from 161 to 180 AD and a Stoic philosopher. He was the last of the rulers known, noncontemporaneously, as the Five Good Emperors and the last emperor of the Pax Romana, an age of relative peace, calmness and stability for the Roman Empire lasting from 27 BC to 180 AD.
