Marcus Aurelius Antoninus was born on April 26, A.D. 121. His real name was M. Annius Verus, and he was sprung of a noble family which claimed descent from Numa, second King of Rome. Thus the most religious of emperors came of the blood of the most pious of early kings. His father, Annius Verus, had held high office in Rome, and his grandfather, of the same name, had been thrice Consul. Both his parents died young, but Marcus held them in loving remembrance. On his father's death Marcus was adopted by his grandfather, the consular Annius Verus, and there was deep love between these two. On the very first page of his book Marcus gratefully declares how of his grandfather he had learned to be gentle and meek, and to refrain from all anger and passion. The Emperor Hadrian divined the fine character of the lad, whom he used to call not Verus but Verissimus, more Truthful than his own name. He advanced Marcus to equestrian rank when six years of age, and at the age of eight made him a member of the ancient Salian priesthood.
