Messalina

Valeria Messalina (; ) was the third wife of Roman emperor Claudius. She was a paternal cousin of Emperor Nero, a second cousin of Emperor Caligula, and a great-grandniece of Emperor Augustus. A powerful and influential woman with a reputation for promiscuity, she allegedly conspired against her husband and was executed on the discovery of the plot. Her notorious reputation may have resulted from political bias, but works of art and literature have perpetuated it into modern times.

==Early life== Messalina was the daughter of Domitia Lepida and her first cousin Marcus Valerius Messalla Barbatus. Her mother was the youngest child of the consul Lucius Domitius Ahenobarbus and Antonia Major. Her mother's brother, Gnaeus Domitius Ahenobarbus, had been the first husband of the future Empress Agrippina the Younger and the biological father of the future Emperor Nero, making Nero Messalina's first cousin despite a seventeen-year age difference. Messalina's grandmothers Claudia Marcella the Younger and Antonia the Elder were maternal half sisters. Claudia Marcella Minor, Messalina's paternal grandmother, was the daughter of Augustus' sister Octavia the Younger. Antonia Major was the elder daughter of Octavia by her marriage to Mark Antony, and was Claudius' maternal aunt. There was, therefore, a large amount of inbreeding in the family.
