Portrait of a Young Girl is a small oil-on-oak panel painting by the Early Netherlandish painter Petrus Christus. It was completed towards the end of his life, between 1465 and 1470, and is held in the Gemäldegalerie, Berlin. It marks a major stylistic advance in contemporary portraiture; the girl is set in an airy, three-dimensional, realistic setting, and stares out at the viewer with a complicated expression that is reserved, yet intelligent and alert.
It is widely regarded as one of the most exquisite portraits of the Northern Renaissance. Art historian Joel Upton described the sitter as resembling "a polished pearl, almost opalescent, lying on a cushion of black velvet." The panel builds on the work of Jan van Eyck and Rogier van der Weyden, and was highly influential in the decades after its completion. Its appeal lies in part in her intriguing stare, accentuated by the slight misalignment of her eyes, while the eyebrows are faintly skewed.
Christus frames his sitter in a rigid and balanced architectural setting. She is positioned within a narrow rectangular space, before a wainscotted wall. The image is divided by the horizontal parallel lines of her wainscot and blouse, which join at the inverted triangle formed by the neckline of her dress. The rendering of the background departs somewhat from contemporary conventions in portraiture: Christus sets the girl against a dark brown wall with little detail, in contrast to the elaborate interiors of Jan van Eyck, who is often regarded as Christus' master. It is defined entirely by its material, a wooden dado rail along the top and the wainscot that forms the lower portion. The wall sets her in a realistic interior, perhaps intended to represent a space within her home.
Light falls on the pictorial space from the left, creating shadows against the back wall, the strongest cast by the girl's hennin. The depth of space provided by the back wall gives room for this detailing, which Charles Sterling believes is indebted to van Eyck. The light throws a murky but curved shadow on the wall behind the girl and acts as a counterpoint to the contour of her cheek and hairline.
