This is pretty amazing, and one of the easier to read translations of the journal(s) of Marcus Aurelius, one of the Roman Emperors. This is disjoint chunks of information and ideas, some repeated, some with references long lost.

It serves as his journal during his leadership time, and probably served as his outlet for things he could not say given his position.

I would not recommend powering through this. Read it in bits, ponder, and then come back to it.
