The British Palladian or 'Kent' frame, with its distinctive outset corners, is called after the architect and designer William Kent (1685-1748); he derived it from the late Mannerist work of Michelangelo, interpreted by Palladio and Inigo Jones.
The painting and its frame were completely integrated with the overall setting. The 'Kent' frame was decorated with strong classical mouldings, such as egg-&-dart, ribbon-&-stave and Greek fret.

This beautiful portrait is an 18th century head and shoulders version of the large three quarter length painted by Sir Godfrey Kneller for Queen Mary's collection, the Hampton Court Beauties.
