Margaret Newton (née Coningsby), Countess of Coningsby in the Costume of the Charlton Hunt

Margaret Newton, Countess of Coningsby in the Costume of the Charlton Hunt from 1760 by George Stubbs depicts the countess in the distinctive livery of the Charlton Hunt, one of the most prestigious hunts in England. The participation of aristocratic women in hunting and riding culture was a notable feature of Georgian social life, and their equestrian portraits by Stubbs gave equal prominence to the horse and the rider's costume as signifiers of status. The Charlton Hunt's blue and buff livery identified membership of an exclusive social circle. Stubbs placed the countess in a landscape setting appropriate to the hunt, combining formal portraiture with his characteristic equestrian precision. The work is held at the Yale Center for British Art and represents an early example of Stubbs's ability to handle female equestrian subjects with the same authority as his male commissions.

The hunting portrait combines equestrian skill with costume accuracy, Stubbs rendering both the rider and her mount with characteristic precision.
