The widowed Queen Mariana of Austria wears a nun's habit, directed half left, almost facing front, a book held in her left hand and her right hand resting on the back of a chair on left; a draped blue and gold curtain in the background. The custom of adopting this type of dress was well established among the widows of the Habsburg dynasty in Spain . Mariana's husband, King Philip IV, had died in 1665. While the couple's son, the future Charles II, was very young, Mariana acted as Queen Governor of Spain . Size: 104.7 x 84.1 cm
