The painting, which depicts the Madonna nursing the Child, is called Madonna de ambro from the inscription on the lower edge of the panel, the origin of which, however, is unknown. From the upper limit of the table emerges the circular halo of the Madonna who, indulging in a vein of popular naturalism, has her hair gathered in a twisted cord net with tassel terminations that descend on her shoulders according to an immediate adherence to the cultural heritage of the people for whom the image was created; a heavy crown completes the hairstyle. The features of the drawing are very accentuated, the flat and intense colors, a rigorous frontality and fixity of the gaze characterize the figure of the Virgin, giving the image a solemn majesty. The painting was published by Piccirilli in 1919 as a work of the thirteenth century, the Toesca approached it for the crown and the features of the face to the Madonna of the apse of S. Maria in Foro Claudio; Garrison thought it was done in an Umbrian-Abruzzese environment, dating it to 1270-80. Matthiae was the first to approach the table with Spoleto production, while Bologna, considering it "already in the thirteenth century", underlined its affinities with the production of A. Sotio and with the frescoes of Rongolise. BosKovits, looking for the cultural matrices of the Third Master of Anagni, attributed the work to Alberto Sotio himself, thus confirming the early dating to the first quarter of the 13th century.
