Titan Fine Art has dated this piece to the 17th Century.
In 1662 she married Joceline Percy, 11th Earl of Northumberland, joining one of England’s greatest dynasties and its world of estates, display, and court visibility. Widowed young, she married in 1673 Ralph Montagu (later 1st Duke of Montagu), English ambassador in France, placing her at the crossroads of aristocratic authority and the French-influenced sophistication that defined Restoration taste.

The portrait’s broader significance lies in its proximity to the “Windsor Beauties,” Lely’s famed early-1660s series for Anne Hyde, Duchess of York—a programme that turned glamour into a statement of legitimacy and courtly power. Lely’s approach, celebrated for creating an idealised courtly type rather than strict likeness, became the standard of the age and encouraged studio versions for allied households and collectors.

The sitter’s mid-1660s costume—open neckline, softly bared shoulder, luminous sleeves, and pearls—signals controlled intimacy and rank, while the column, architecture, and landscape provide classical stagecraft. Its scale and design suit high-status display: compelling at close range in the head and flesh, yet commanding from across a room in drapery and setting. In this sense, it is a direct product of the workshop that defined Restoration England’s visual language.
