Domitilla niece (or wife) of Flavius Clemens, who was put to death under Domitian (q.v.; Euseb. 3:18). It is not certain that they were Christians, but it is at least probable. Domitilla did not suffer martyrdom, but was banished; an unwarranted tradition says that she was afterwards burnt under Trajan. She is commemorated as a saint in the Roman Church, May 12. See Butler, Lives of Saints, May 12; Tillemont, Memoires, 2:124; Murdoch's Mosheim, Church History, N.Y. ed., 1:59.
