Sextus3. Of Chaeroneia, a Stoic philosopher, nephew of Plutarch, and one of the instructors of the emperor Marcus Aurelius (Jul. Capitolin. Vita M. Antonin. Philos. ; Suid. s. v. Μάρκος; comp. Antonin. De Rebus suis, 1.9). According to Suidas it was during the reign, and indeed in the latter part of the reign of Marcus, and when Sextus was teaching at Rome, that the emperor attended his instructions. He is perhaps the " Sextus the Philosopher," mentioned by Syncellus as flourishing under the reign of Hadrian.
Confusion of Sextus of Chaeroneia with Sextus EmpiricusSuidas (s. v. Σέξτος Χαιρωνεὺς) confounds the nephew of Plutarch with a contemporary or nearly contemporary philosopher, Sextus Empiricus [SEXTUS EMPIRICUS : and this confusion, into which several modern critics have also fallen, makes it difficult to determine to which of the two the particulars mentioned by him in the article are to be referred. When he states that Sextus was the disciple of Herodotus of Philadelphia, and was so high in the favour of the emperor Marcus Aurelius, that he was invited to share with him the judgment-seat, it is probable that our Sextus is spoken of. To him also we may suppose the account to refer, that an impostor, who resembled him in features, attempted to personate him, and thus to obtain possession of his honours and property. The impostor is said to have been discovered, through his ignorance of Greek learning, by the emperor Pertinax.
Ἠθικά, Ethica, and Ἐπισκεπτικά, βιβλία δέκα, Episceptica (for which some propose to read Σκεπτικά, Sceptica, or ἔτι Σκεπτικά), Libris decem. Menage (vid. Kuster, Not. in Suid.) suspects that the mention of the second work has been inserted by some transcriber, who confounded the two Sexti above mentioned; but the mistake (if such it be) is probably to be attributed to Suidas himself or the authority from whom he took it, for we find it also in the Ionia of the empress Eudocia.
