Cassius Dio mentions that Domitian (ruled 81-96 CE) did not shy away from spilling blood among his family as well. On his order, Flavius Clemens was related to him, grandson of Titus Flavius Sabinus (brother of Vespasian, and uncle of Domitian) and the husband of his niece, Flavia Domitilla.
As it turned out, the reason for the death of Clemens, who, incidentally, in 95 CE he had a consulate with Domitian, there was “atheism”, or more precisely, a conversion to the Jewish religion. Probably, if you believe the messages of Cassius Dio, it may be about Christianity.
Flavia Domitilla was also accused of atheism, but she, for a change, was expelled to the island of Pandataria (Ventotene, west of Italy).
