a sister of Cn. Domitius Ahenobarbus [AHENOBARBUS, No. 10], and of Domitia, and, consequently, like her an aunt of the emperor Nero. She was married to M. Valerius Messalla Barbatus, by whom she became the mother of Messallina, the wife of the emperor Claudius. There existed a rivalry of female vanity between her and Agrippina, the mother of Nero. Both wonen were equally bad and vicious in their conduct; Agrippina however succeeded, in A. D. 55, in inducing her son to sentence his aunt to death. (Tac. Ann. 11.37, &c., 12.64, &c. ; Suet. Cl. 26, Nero, 7.)
