Madonna Casini

Masaccio applied tempera on a gold-ground panel, employing a palette of deep blue, vermilion red, creamy white, and extensive gold leaf. The surface shows fine craquelure and features smooth, precise brushwork that yields a polished, enamel-like finish. While the unmodulated gold background and flat, finely incised halos retain a medieval character, the construction of the figures is highly innovative. The group is rotated three-quarters and offset from the center, suggesting a sense of passage through space. No prior work features such a pronounced rotation of the shoulders, lending the composition an unprecedented naturalism. Natural light falls from the left, casting soft shadows and leaving parts of the faces in shadow, a departure from even, traditional illumination. The Virgin's left hand, which supports the weight of the child, is broadly sketched but highly expressive. Her dark blue mantle features a gold-trimmed edge with pseudo-Kufic characters that conform to the volume of her body, enhancing the sense of sculptural mass. The richness of detail, distinct from the essentiality of the Brancacci Chapel, suits the small format and invites close contemplation.

The panel was almost certainly commissioned for private devotion by Antonio Casini, a Sienese cardinal, jurist, and canonist. His coat of arms, accompanied by a cardinal's hat, is painted on the reverse, suggesting the work dates to or shortly after his appointment as cardinal on May 26, 1426. Casini likely chose Masaccio after the painter Masolino departed for Hungary. The early history of the painting remains unknown. It was discovered in 1947 by Rodolfo Siviero, who recovered it among masterpieces looted by the Germans during World War II. Later, while on display in the Loeser collection at Palazzo Vecchio, the panel was stolen in 1971. Siviero recovered it again two years later, in 1973. The painting entered the Uffizi Gallery collection in 1988.

The attribution of the Madonna Casini to Masaccio was first proposed by Roberto Longhi in 1950, who connected the work stylistically to Masaccio's Desco da parto, another private commission featuring a similarly plump and lively child. While some scholars initially disputed this attribution, the publication of Franco Berti's Masaccio catalog in 1954 secured its widespread acceptance. The painting reflects the milieu of its patron, the cultured Cardinal Casini, who was connected to humanists and figures like Branda Castiglione. The unusual iconography, which had a precedent in Andrea Pisano's lunette on Giotto's campanile, was permissible in the context of private devotion, where conventional restraints were relaxed. The work stands as a key monument in Masaccio's oeuvre, bridging the medieval gold-ground tradition and the revolutionary spatial and volumetric developments of the early Italian Renaissance.
