Agaclytus was a freedman of Roman Emperor Marcus Aurelius, said to have had great influence over Aurelius and his co-emperor, Lucius Verus.[1] He was given in marriage to the widow of Marcus Aurelius' cousin, Marcus Annius Libo by Verus, over the objections of Aurelius, who declined to attend the wedding banquet.[2] It is one of the few—if not only—examples in ancient Rome of a freedman marrying someone from the senatorial class.[3] Agaclytus's son by this marriage, Lucius Aurelius Agaclytus, went on to become the second husband of Vibia Aurelia Sabina, the youngest daughter of Aurelius. The Augustan History reports a rumor that a plot against Marcus Aurelius fomented by his wife, Faustina the Younger, was quashed when Agaclytus reported its existence to Aurelius; however, there were numerous rumors of Faustina's misbehavior, and Aurelius vigorously denounced them all as untrue.[1][4]
