Caenis

According to Cassius Dio, 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, Suetonius states that she was treated with disrespect by Vespasian's son Domitian, who refused to greet her as one of the family.

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.
