Thomas Gainsborough famous portrait of the dancer GIOVANNA BACCELLI. tate.

I believe she became the mistress of the duke of Dorset and went to live with him at Knole. The English servants couldn’t pronouce her name and her rooms at Knole are known to this day as Shelly’s tower. There is a rather winsome sculpture of her nude at the foot of the staircase at Knole.
