Intricate braided and interlaced patterns, called plaits in British usage, first appeared in late Roman art in various parts of Europe, in mosaic floors and other media.
By about 700 it becomes less common in most of Europe, but continues to develop in the British Isles and Scandinavia, where it is found on metalwork, woodcarving, runestones, high crosses, and illuminated manuscripts of the 7th to 12th centuries.
[1] Art historian James Johnson Sweeney argued for direct communication between the scriptoria of Early Christian Ireland and the Coptic monasteries of Egypt.
[1] The most elaborate interlaced zoomorphics occur in Viking Age art of the Urnes style (arising before 1050), where tendrils of foliate designs intertwine with the stylized animals.
Umayyad architectural elements such as floor mosaics, window grilles, carvings and wall paintings, and decorative metal work of the 8th to 10th centuries are followed by the intricate interlacings common in later medieval Islamic art.
