The major sources depicting the life and rule of Marcus Aurelius are patchy and frequently unreliable. The most important group of sources, the biographies contained in the Historia Augusta, claimed to be written by a group of authors at the turn of the 4th century AD, but it is believed they were in fact written by a single author (referred to here as 'the biographer') from about 395.
