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 spread 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.

They were called μεσαία kακαβιά or κυτροκακάβια where the former had a bulbous shape and the latter a more cylindrical form.
