LITERATURE:
See Boito, C., Architettura Cosmatesca, Torino, 1860; Hutton, E., The Cosmati, The Roman Marble Workers of the XIIth and XIIIth Centuries, London, 1950; Tosca, P., Storia dell’Arte Italiana, il medioevo, vol. III, Torino, 1965; Matthiae, G., 'Componenti del gusto decorativo cosmatesco,' in Rivista dell'Istituto Nazionale di Archeologia e Storia dell'Arte, vol. I, 1952, pp.249–281; Cigola, M., 'Mosaici pavimentali cosmateschi. Segni, disegni e simboli,' in Palladio, Nuova serie, anno VI n. 11, Giugno, 1993, pp.101–110; the composition of the mosaic recalls the floors of the most important churches in Rome, like the floor of the Sistine Chapel (realised probably in 14th century for the previous building or Cappella Maggiore), or that of Santa Maria Maggiore (1145-1153 A.D.), San Giovanni in Laterano (14th century A.D.), Saint Clement (1099-1120 AD), Santi Quattro Coronati (13th century A.D.), Santa Croce in Gerusalemme (12th century A.D.) and many others.

FOOTNOTES:
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 A.D. 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.
