Meditations

Meditations is the title of a series of personal writings
by Marcus Aurelius setting forth his ideas on Stoic philosophy.

Marcus Aurelius wrote the 12 books of the Meditations in Greek as a
source for his own guidance and self-improvement. It is possible that large
portions of the work were written in Sirmium, where he spent much time planning
military campaigns from 170 to 180. We know that some of it was written while he
was positioned at Aquincum on campaign in Pannonia, because internal notes tell
us that the second book was written when he was campaigning against the Quadi on
the river Granova (modern-day Hron) and the third book was written at Carnuntum.
It is not clear that he ever intended the writings to be published, so the title
Meditations is but one of several commonly assigned to the collection.
These writings take the form of quotations varying in length from one sentence
to long paragraphs.
