Geburt Christi

It shows his usual harmonious composition and employment of one-point-perspective, especially evident in the geometric forms of the shed's roof, and his bold use of color. It is one of Christus's most important works. Max Friedländer definitely attributed the panel to Christus in 1930, concluding that "in scope and importance, [it] is superior to all other known creations of this master."

The overall atmosphere is one of simplicity, serenity and understated sophistication. It is reflective of the 14th-century Devotio Moderna movement, and contains complex Christian symbolism, subtly juxtaposing Old and New Testament iconography. The sculpted figures in the archway depict biblical scenes of sin and punishment, signaling the advent of Christ's sacrifice, with an over-reaching message of the "Fall and Redemption of humankind". Inside the archway, surrounded by four angels, is the Holy Family; beyond, a landscape extends into the far background.

Art historians have suggested completion dates ranging from the early 1440s to the early 1460s, with c. 1455 seen as probable. The panel was acquired by Andrew Mellon in the 1930s, and was one of several hundreds from his personal collection donated to the National Gallery of Art in Washington. It has suffered damage and was restored in the early 1990s for an exhibition at the Metropolitan Museum of Art.
