Sophie Dawes - the surviving images
There are very few surviving images of Sophie Dawes. And these are mostly from the latter half of her life, after she became Baronne de Feuchères and when she was perhaps no longer quite the beauty that first attracted the attention of the Duc de Condé in Regency London. It is almost certain, however, that she would have commissioned one or two formal, full-scale portraits by well-known and accomplished artists. But these were possibly destroyed after her death.
This is a great shame. One longs for a portrait to be unearthed from the accomplished hand of someone like Winterhalter, who painted many of her contemporaries. But, as the novel makes clear, Baronne de Feuchères left behind many enemies. Among these were people in positions of considerable power and influence.
