Task: Question Answering
Input (English): Passage: The woman's hands are crossed tightly as if in prayer, and positioned so low in the painting as to appear to be resting on the frame. They are rendered as tightly compressed into a small area of the picture; it is likely van der Weyden did not want them to result in an area of high tone that might distract from the description of her head. Her slender fingers are minutely detailed; van der Weyden often indicated the social position of his models through his rendering of their face and hands. The sleeve of her dress extends beyond her wrists. Her fingers are folded in layers; their intricate portrayal is the most detailed element in the painting, and echoes the pyramidal form of the upper portion of the painting.Her eyes gaze downward in humility, in contrast to her relatively extravagant clothes. The piety of her expression is achieved through motifs common to van der Weyden's work. Her eyes and nose are elongated and her lower lip made fuller by the use of tone and pronounced finish. Some vertical lines around these features are emphasised, while her pupils are enlarged and her eyebrows slightly raised. In addition the contours of her face are highlighted in a manner that is slightly unnatural and abstract, and outside the usual spatial constraints of 15th-century human representation. This methodology was described by art historian Erwin Panofsky: "Rogier concentrated on certain salient features—salient both from a physiognomical and psychological point of view—which he expressed primarily by lines." Her high forehead and full mouth have been seen as suggestive of a nature at once intellectual, ascetic, and passionate, symbolic of "an unresolved conflict in her personality". Panofsky refers to a "smouldering excitability".The sitter is unknown, although some art historians have speculated on her identity. On the grounds of similarity of facial features, writer Wilhelm Stein suggested in the early 20th century that she might be Marie de Valengin, the illegitimate daughter of Philip the Good of Burgundy. However, this is a contentious assertion and not widely held. Because her hands are shown as resting on the painting's lower frame, art historians generally accept that this was an independent portrait, rather than a devotional work. It is possible that it was intended as a pendant to a picture of the woman's husband, however no other portrait has been suggested as a likely companion.
