Show me his personal journal in Latin.

Nevermind that Meditations was his personal journal, show me this latin version.

Thanks for trying to give me a lesson in a language I've been intimately familiar with for 30+ years.

Latin was the princiapl government and military language of the Roman Empire (though the Roman Empire had two official languages), and the most commonly used language in the western reaches especially in administration. However, around the Mediterranean and further east Greek was principally used since it was the language of commerce and had been well established for centuries prior to the establishment of the empire. Not long after Diocletian effectively split the Empire in two, the eastern half dropped Latin entirely as an official language. They weren't really using it much and teaching your fresh recruits and bureaucrats a new language when you both already spoke a common one was pretty pointless.
