Written in Greek without any intention of publication, a book by the 2nd century Roman emperor offers spiritual reflections and exercises developed by the author, as a leader who struggled to understand himself and make sense of the universe, covering such topics as the question of virtue, human rationality, the nature of the gods, and Aurelius's own emotions. This edition includes a selection of the correspondence between Marcus Aurelius and his former tutor, the rhetorician Marcus Cornelius Fronto.
