Given the following context:

The panel is the smallest extant work by van der Weyden and follows the tradition of a Madonna Lactans, with significant differences. Christ is dressed in a red garment, as opposed to the swaddling he usually wears in 15th-century Virgin and Child portrayals. This is one of two exceptions where he is fully clothed; the other is Robert Campin's Madonna in Frankfurt, where he is shown in blue clothing. Mary's unbound blond hair falls across her shoulders and down across her arms. Showing the influence of Campin, it is brushed behind the ears. She wears a crown as Queen of Heaven and a ring on a finger as the Bride of Christ. Reinforcing this, the blue colour of her robe alludes to her devotion and fidelity to her son.

The Virgin and Child are shown seated in a small Gothic chapel or oratory projecting from a wall and opening onto a lawn. The painting pays very close attention to small realistic detail; for example, there are four small holes above each arch, likely to hold scaffolding.
As with other early van der Weyden depictions of the Madonna, her head is slightly too large for her body. Her dress is creased and almost paper-like.

This seems to reflect an early difficulty both with foreshortening and in the depiction of a body under clothing.The chapel is unrealistically small compared to the Virgin; van der Weyden's intention was to emphasise the Virgin's presence while also symbolically representing the Church and the entire doctrine of the Redemption. The panel is one of three surviving of van der Weyden's in which both Madonna and...
