In the middle of the war, perhaps in autumn 163 or early 164, Lucius made a trip to Ephesus to be married to Marcus's daughter Lucilla. Marcus moved up the date; perhaps he had already heard of Lucius's mistress Panthea. Lucilla's thirteenth birthday was in March 163; whatever the date of her marriage, she was not yet fifteen. Lucilla was accompanied by her mother Faustina and Lucius's uncle (his father's half-brother) M. Vettulenus Civica Barbarus, who was made "comes Augusti", 'companion of the emperors'. Marcus may have wanted Civica to watch over Lucius, the job Libo had failed at. Marcus may have planned to accompany them all the way to Smyrna (the biographer says he told the senate he would), but this did not happen. He only accompanied the group as far as Brundisium, where they boarded a ship for the east. He returned to Rome immediately thereafter, and sent out special instructions to his proconsuls not to give the group any official reception.
