The Fortunate Mistress or a History of the Life of Mademoiselle de Beleau, Known by the name of the Lady Roxana (1724)

According to Wikipedia: "Roxana: The Fortunate Mistress is a 1724 novel by Daniel Defoe. The full title of the novel is Roxana: The Fortunate Mistress Or, a History of the Life and Vast Variety of Fortunes of Mademoiselle de Beleau, Afterwards Called the Countess de Wintselsheim. The novel concerns the story of an unnamed "fallen woman", the second time Defoe created such a character (the first was a similar female character in Moll Flanders). In Roxana, a woman who takes on various pseudonyms, including "Roxana," describes her fall from wealth thanks to abandonment by a "fool" of a husband and movement into prostitution upon his abandonment. Roxana moves up and down through the social spectrum several times, by contracting an ersatz marriage to a jeweler, secretly courting a prince, being offered marriage by a Dutch merchant, and is finally able to afford her own freedom by accumulating wealth from these men."
