The Cosmatesque style was a characteristic type of ornamentation of Eastern Roman origin (opus alexandrinum) used by the Roman marble makers of the 12th and 13th centuries AD. It embellishes floors, ciboriums and cloisters of churches by means of polychrome marble inlays of varied and imaginative geometric shapes. The wider use of this decoration began in the 12th century, at which time techniques were improved: the Cosmati floors were made with pieces of stone cut in various shapes and sizes, a property quite different from the mosaics in opus tessellatum, in which the motifs were made from small units all having the same size and shape, or from the opus sectile, intended to create representations with pieces of multicoloured marble cut out and arranged for this purpose. The stones used by Cosmati artists were often material salvaged from the ruins of ancient Roman buildings.

The small square plaque was possibly part of the decoration of an Evangeliary, such as the enamels covering the binding of Henry II's Perikopenbuch, or the Siena Evangeliary (11th-13th century). Byzantium brought the enamel and cloisonné technique to its most perfect, refined and skilful expression. Between the 10th and 11th centuries it spreads its forms in the East and West and after some infiltration in the Romanesque-Lombard sphere, precious Eastern Roman cloisonnes were found in Russian art, reaching their apex in the Roman Empire during the 10th-12th centuries, in the decoration of icons and other artworks.
