[Sidenote: A.D. 161 (a.u. 914)] [Sidenote:--1--] Marcus Antoninus, the philosopher, upon obtaining the sovereignty at the death of Antoninus, who adopted him, had immediately taken to share the authority with him the son of Lucius Commodus, Lucius Verus. He was personally weak in body and he devoted the greater part of his time to letters. It is told that even when he was emperor he showed no shame (or hesitation) at going to a teacher for instruction, but became a pupil of Sextus, the Boeotian philosopher, [Footnote: "Sextus of Chaeronea, grandson of Plutarch" (Capitolinus, _Vita M. Antoni Philosophi_, 3, 2).] and did not hesitate to go to hear the lectures of Hermogenes on rhetoric. He was most inclined to the Stoic school. Lucius, on the other hand, was strong and rather young, and better suited for military enterprises. Therefore, Marcus made him his son-in-law by marrying him to his daughter Lucilla, and sent him to the Parthian war.
