4. Q.JuniusRusticus, probably a son of No. 3, and grandson of No. 2, was one of the teachers of the emperor M. Aurelius, and the most distinguished Stoic philosopher of his time. He received the greatest marks of honour from Aurelius, who constantly consulted him on all public and private matters, raised him twice to the consulship, and obtained from the senate after his death erection of statues to his honour. His name, however, appears only once in the consular Fasti, namely, in A. D. 162. (D. C. 71.35 ; Capitol. M. Antonin. Phil. 3; Antonin. 1.7, with the note of Gataker.)
