Pomponia married
Aulus Plautius (d. by 65 AD), the
senator and general who led the Roman conquest of Britain in 43 AD, for which he later received a military
ovation, and who governed
Roman Britain until 47 AD. A younger Aulus Plautius, probably their son, was murdered by the emperor Nero, supposedly because Nero's mother Agrippina had fallen in love with him and encouraged him to bid for the throne. In 43 AD Pomponia's relative Julia Livia, daughter of her uncle
Drusus Julius Caesar, was executed on the orders of her maternal uncle, the emperor
Claudius at the instigation of the empress
Valeria Messalina. Pomponia spent the next forty years in open mourning in defiance of successive emperors. She escaped punishment for this, possibly as a result of her own illustrious ancestry and her husband's sterling military reputation, which gave her prestige. According to
Tacitus, Pomponia lived a long, unhappy life, possibly as a result of her son's murder and the deaths of several relatives associated with the Imperial family. In 57 AD Pomponia was charged with practising a "foreign superstition", which has been taken by some to mean conversion to
Christianity, although there were other regulated cults in ancient Rome. According to ancient Roman tradition, she was tried by her husband before her kinsmen, and acquitted. She died in 83 AD.
Inscriptions in the catacombs of Saint Callistus in
Rome suggest that later members of Pomponia's family were indeed Christians. The archaeologist Battista de Rossi controversially identifies her with
Saint Lucina, the purported donor of the part of the catacombs where the inscriptions were found, and suggests that Lucina was Pomponia's baptismal name. Saint Lucina is honoured by the
Roman Catholic Church on 30 June. She is said to have visited the martyrs
Martinian and Processus, the two former guards at the
Mamertine Prison who had been converted in prison by their prisoner
Saint Peter, and buried their bodies after their execution. ==Fictional depictions==
