[3] Marco Agosti identified him as Instanius (sometimes corrected as Instantius, Insantius, Istantius or Istanius) Rufus, a patron of Martial.

[4] According to Cassius Dio, the two entered into an affair some time before their marriage, either late in AD 39 or early in 40, and the emperor's choice of a bride was an unpopular one.

Josephus reports that she died bravely: stricken with grief at her husband's death, she willingly offered her neck to the assassin, telling him to kill her without hesitation.
