Marcus Aurelius was born in 121 C.E.. His early education was overseen by the Emperor Hadrian, and he was later adopted by the Emperor Antoninus Pius in 138 C.E.. After an initial education in rhetoric undertaken by Fronto, Marcus later abandoned it in favor of philosophy. Marcus became Emperor himself in AD 161, initially alongside Lucius Verus, becoming sole Emperor in AD 169. Continual attacks meant that much of his reign was spent on campaign, especially in central Europe. However, he did find time to establish four Chairs of Philosophy in Athens, one for each of the principal philosophical traditions (Platonic, Aristotelian, Stoic, andEpicurean). He died in AD 180.
Marcus' reputation as a philosopher rests upon one work, the Meditations. The Meditations take the form of a personal notebook and were probably written while Marcus was on campaign in central Europe, c. AD 171-175. The entries appear to be in no particular order and may simply be in the original order of composition. The repetition of themes and the occasional groups of quotations from other authors (see e.g. Med. 4.46, 11.33-39)add to this impression. Book One, however, is somewhat different from the rest of the text and may well have been written separately (a plan for it may be discerned in Med. 6.48).
The first recorded mention of the Meditations is by Themistius in AD 364. The current Greek title - ta eis heauton ('to himself') – derives from a manuscript now lost and may be a later addition (it is first recorded c. AD 900 by Arethas). The modern text derives primarily from two sources: a manuscript now in the Vatican and a lost manuscript (mentioned above), upon which the first printed edition (1558) was based.
Beyond the Meditations there also survives part of a correspondence between Marcus and his rhetoric teacher Fronto, probably dating from earlier in Marcus' life (c. AD 138-166), discovered as a palimpsest in 1815. However, although this interesting discovery sheds some light on Marcus as an individual, it adds little to our understanding of his philosophy.
