The twisted-cable type of patterns is found as Late Roman–Byzantine and early Umayyad floor patterns, with considerable uniformity in texture, colors, and technique. They consist of ‘cables’ which together form circles, circle segments, squares and other visually prominent ornamental elements. Cables mostly form complex closed loops, joined at points of local overlap by interlocking ‘knots’. The loops are the inconspicuous construction elements and several of them participate in each visually prominent segmented circle, square, etc. Majority of these patterns are tetragonal with chiral character, with predominant 2D layer-group symmetry p 422. Other symmetries are rare, mostly in circular designs. Most of patterns were dichroically colored using local marbles. The combination of loops and knots generates broad versatility of design and a rich spectrum of extant patterns. The principal artistic heritage of this mosaic style are the Cosmatesque floor patterns of central Italy.

联锁双绞电缆环的拜占庭地板模式

扭曲电缆类型的图案被发现为晚期罗马-拜占庭和早期倭马亚时期的地板图案，在质地、颜色和技术上具有相当大的一致性。它们由“电缆”组成，它们一起形成圆形、圆段、正方形和其他视觉上突出的装饰元素。电缆大多形成复杂的闭环，通过互锁的“结”在局部重叠点连接。环是不显眼的构造元素，其中一些参与每个视觉上突出的分段圆形、方形等。这些图案中的大多数是具有手性特征的四边形，主要是二维层组对称 p 422。其他对称性很少见，主要在圆形设计。大多数图案使用当地的大理石进行二色着色。环和结的组合产生了广泛的设计多功能性和丰富的现存图案。这种马赛克风格的主要艺术遗产是意大利中部的 Cosmatesque 地板图案。
