It could be thought that she had family in Istria, now in Croatia, based on a trip she took there (Suet. Dom. 12.3). In her 30s Caenis, still possibly a slave, was in an unofficial type of relationship with Vespasian, known as contubernium,[5] before his marriage. According to Suetonius, after the death of Vespasian's wife Flavia Domitilla, Vespasian and Caenis, now a freedwoman, resumed their relationship; she was his wife "in all but name" until her death in AD 75.
She had a remarkable memory and considerable influence on the emperor's administration, carried out official business on his behalf, and apparently made a lot of money from her position.[6] However, she was treated with disrespect by Vespasian's son Domitian, who refused to greet her as one of the family.[7]

Inscription commemorating Caenis, described by the historian Suetonius as the "almost wife" of Vespasian[8]
The life of Caenis and her love-story with Vespasian are portrayed in Lindsey Davis's novel The Course of Honour.
She is also a character who features regularly in Robert Fabbri's Vespasian series, in which she is depicted as a long-lost grand-niece of the king of the Caenii, a rebelling tribe in Thracia.
Robert Graves, in his short story "Caenis on Incest", used her as a kind of foil to present what he then thought to have been the underlying reason for the power-related murders chronicled in I, Claudius. The story is included in his compendium "Occupation: Writer", and he admits to having missed the real reason for the murders in the introduction to that anthology. [9]
