Domitian kills his Cousin
Contributed by David Verne
Domitian appoints his cousin, Titus Flavius Clemens, as his co-counsel this year, however, Domitian then decides to put his cousin to death on charges of atheism. According to Roman historian, Cassius Dio, this meant Clemens had become Jewish or Christian, with the former more likely. Domitian then executed his secretary Epaphroditos, a freedman who had helped Nero with his suicide, accusing him of not doing enough to try and save his master. After this execution, Domtian's once loyal court officials began fearing for their lives and a plot was hatched to assassinate him, lead by his chamberlain, Parthenius.
