The woman, who is probably in her late teens or early twenties, is shown half-length and in three-quarters profile, set against a two-dimensional interior background of deep blue-green. The background is
flat and lacks the attention to detail common in van der Weyden's devotional works. Like his contemporary
Jan van Eyck (c. 1395 – 1441), when working in portraiture, he used dark planes to focus attention on the sitter. It was not until
Hans Memling (c. 1435–1494), a pupil of van der Weyden, that a Netherlandish artist set a portrait against an exterior or landscape. In this work the flat setting allows the viewer to settle on the woman's face and quiet self-possession.|alt=see caption and text The woman wears an elegant low-cut black dress with dark bands of fur at the neck and wrist. Her clothes are of the then-fashionable
Burgundian style, which emphasises the tall and thin aesthetic of the
Gothic ideal. Her dress is buckled by a bright red sash pulled in below her breasts. The
buff-coloured hennin headdress is draped with a large transparent veil, which spills over her shoulders, reaching her upper arms. Van der Weyden's attention to the structure of the clothing—the careful detailing of the pins pushed into the veil to fix its position—is typical for the artist. The woman's veil forms a diamond shape, balanced by the inverse flow of a light vest worn beneath her dress. She is shown at a slight angle, but her pose is centred by the interlocked broad lines of arms,
décolletage and veil. Her hair is tightly pinned back on the rim of the bonnet and rests above her ear. Her high headdress and severe hairline accentuate her elongated face, giving it a sculpted appearance. 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. and outside the usual spatial constraints of 15th-century human representation. 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. ==Break from idealisation==
