William II, Prince of Orange, and his Bride, Mary Stuart, Anthony van Dyck, 1641
The boy is fourteen and the girl only nine. William’s father, Frederick Henry, commissioned the celebrated Flemish painter Van Dyck to portray the young Dutch prince and English princess on the occasion of their marriage in London. The union with the daughter of the English king enhanced the status of the House of Orange. On her gown, Mary wears a gift from William, a large diamond brooch.
