Francesca da Rimini

Francesca da Rimini or Francesca da Polenta (1255–ca. 1285) was the daughter of Guido da Polenta, lord of Ravenna. She was a historical contemporary of Dante Alighieri, who portrayed her as a character in the Divine Comedy.

Daughter of Guido I da Polenta of Ravenna, Francesca was wedded in or around 1275 to the brave, yet crippled Giovanni Malatesta (also called Gianciotto; "Giovanni the Lame"), son of Malatesta da Verucchio, lord of Rimini. The marriage was a political one; Guido had been at war with the Malatesta family, and the marriage of his daughter to Giovanni was a way to solidify the peace that had been negotiated between the Malatesta and the Polenta families. While in Rimini, she fell in love with Giovanni’s younger (and still hale) brother, Paolo. Though Paolo too was married, they managed to carry on an affair for some ten years, until Giovanni ultimately surprised them in Francesca’s bedroom sometime between 1283 and 1286, killing them both.

In the years following Dante's portrayal of Francesca, legends about Francesca began to crop up. Chief among them was one put forth by poet Giovanni Boccaccio in his commentary on The Divine Comedy, Esposizioni sopra la Comedia di Dante; he stated that Francesca had been tricked into marrying Giovanni through the use of Paolo as a proxy. Guido, fearing that Francesca would never agree to marry the crippled Giovanni, had supposedly sent for the much more handsome Paolo in Giovanni's stead. It wasn't until the morning after the wedding that Francesca discovered the deception. This version of events, however, is very likely a fabrication. It would have been nearly impossible for Francesca not to know who both Giovanni and Paolo were, and to whom Paolo was already married, given the dealings the brothers had had with Ravenna and Francesca's family. Also, Boccaccio was born in 1313, some 27 years after Francesca’s death, and while many Dante commentators after Boccaccio echoed his version of events, none before him mentioned anything similar.
