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.
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".
[a] Art historian Joel Upton writes that with its size, style, tone and composition, Christus painted "an Andachtsbild, with monumental, ciboriumlike dimensions".
[10] Mary's features have a softness and sweetness more characteristic of Christus's later paintings and remarkably similar to his Madonna of the Dry Tree, according to Maryan Ainsworth.
[13] Behind the shed is a small hill where two shepherds herd sheep along a pathway,[14] and beyond is a Netherlandish town with two domed structures in its center, symbolizing Jerusalem and Christ's Passion.
"[18] The panel is rich in Christian iconography,[20] which reflects the shift in religious attitudes to a more meditative and solitary devotion in the 14th century, exemplified by the Devotio Moderna movement.
The painting is devotional; its iconography clearly juxtaposes Old and New Testament imagery, conveying themes of punishment and redemption, against the belief that a second chance is available through the birth of Christ.
Robert Campin's c. 1420 Nativity is representative of Bridget's narrative; the cave has been substituted by a shed with animals, Mary's handmaidens are present, while angels and shepherds rejoice.
[6] Earthly sin and strife, anger and revenge, are represented in the warriors in the corner spandrels, and signify that which Christ's birth would bring to an end.
[27] The two reliefs also function as a temporal device, leading the viewer directly to the moment of Christ's birth and mankind's redemption, which occurs below in the shed.
[25] The viewer is reminded that mankind must sacrifice to Christ, who lies directly below, or risk punishment and expulsion from the church, just as God expelled Cain.
[31][c] The confraternity was prestigious, including among its ranks Burgundian nobility, such as Philip the Good and his wife Isabella, wealthy foreign merchants and members from Bruges's upper classes.
A later addition to the painting, added perhaps in the 17th century, and since removed, was a gold paten on which the infant lay, clearly showing Jesus as the Eucharistic host.
[34] Christus was the first Netherlandish painter to achieve proficiency in strict mathematical compositional rules with his use of orthogonals, creating a unified perspective.
The concept of compositions "based on unitary perspective" was largely a pioneering effort on Christus's part, although he borrowed from the earlier masters.
According to art historian Lawrence Steefel, "the detail participates in an almost emblematic pattern of repeated triangles which establish a rhyme scheme above and below, of roof structure and figure disposition.
"[35] Spatial and temporal borders separating the earthly and heavenly spheres are often seen in Netherlandish art, usually in the form of frames or arches.
The multi-hued threshold stones at the bottom emphasize its function says Upton, who writes: "it is an opening through which one passes: a true frame or doorway to the picture ...
Yet, since this arch is painted in grisaille, distinct from the rest of the panel, it must also be seen as a separate entity, much like an elaborate border around an illuminated manuscript page.
Equally, van der Weyden's arched triptychs were executed at roughly the same period, but art historians are more certain Rogier's archivolt design set the precedent.
Mary, Joseph, the Christ child and the four surrounding angels occupy a space partitioned in the front by the archway and by the wall at the rear.
[14] Ainsworth writes that the "message of the painting quietly emerges from the strict, perspectively correct space constructed to engage the viewer.
Estimations range from the mid-1440s to the mid-1450s; early in Christus's career to about the time van der Weyden painted his c. 1455 Saint John Altarpiece.
[37] Ainsworth considers it, along with Christus's Holy Family (currently in Kansas City), one of the most important attributed to him and believes it belongs in his later oeuvre,[41] possibly as late as the mid-1460s.
The dating of the work to the 1440s is based on the notion that Christus borrowed heavily from the immediate influence of van der Weyden and Bouts.
She writes that Bouts and van der Weyden "merely expand the narrative" in their use of the archway motif, whereas Christus shows a strong cause and effect between sin and redemption, innovations which almost certainly evolved later in his career, placing the date no earlier than the mid-1450s.
[42] The underdrawing is visible through modern technical analysis, revealing the main group of figures and contour lines in the folds and drape of the clothing.
[11] The work has suffered damage: cracking where three wood panels are joined, paint loss to parts of the crackle pattern, and discoloration of varnishes.
[2] That April, the Duveen Brothers, less affected by the 1929 stock market crash than other dealers, paid Zatzenstein £30,000, in cash, for the painting and sold it immediately to Mellon.
To avoid the export fees due if the painting been sent directly to New York, the Duveens took a circuitous route – from Madrid to Germany, then to Paris and America.
