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.
