Origins of knots in traditional art
Ornamental knot work, or interlacing, in the decorative arts of Europe and the Middle East originated in the Roman Empire during the third and fourth centuries AD. These beginnings can be seen particulartly in many Roman floor mosaics of that time.
Previous to the developments of Rome, early uses of knots are found in some Egyptian symbols, particularly in the Tyet or Isis knot, and in the Sema which represents the unification of Upper and Lower Egypt. Knots are also frequently found represented in the Egyptian Cartouche and the Ankh.
Celtic art in pagan and Christian times
J. Romilly Allen (1847-1907) published Celtic art in pagan and Christian times in 1904. The book is a scholarly study of Celtic art, and is still often cited as an important source on the subject.
Syriac orthodox Mor Gabriel Monastery (Turkey)

Islamic interlace patterns
Geometric interlacing patterns are a subcategory of Islamic pattern and ornament, and are a particular type of arabesque. Historically, the origins of the Islamic interlace patterns are from the more simple interlace patterns of late Roman and Byzantine mosaics. One of the first Western studies of the subject was E. H. Hankin's "The Drawing of Geometric Patterns in Saracenic Art", published in Memoirs of the Archaeological Societry of India in 1925.
According to Eva Baer, in her book Islamic Ornament:
....the intricate interlacings common in later medieval Islamic art, are already prefigured in Umayyad architecture revetments: in floor mosaics, window grilles, stone and stucco carvings and wall paintings(Khirbat al-Mafjar, Qusayr'Amra, Qasr al-Hayr al-Gharbi etc.), and in the decoration of a whole group of early east Iranian, eighth- to tenth-century metal objects. 
The grace and refinement of Greek ornament is here surpassed. Possessing, equally with the Greeks, an appreciation of pure form, the Moors exceeded them in variety and imagination. 
E. H. Hankin, in his book The Drawing of Geometric Patterns in Saracenic Art, takes the view that the artists who created these designs used a method based on the use of the compass and the straight edge.  This view is supported by the majority of contemporary authorities on the subject, such as Keith Critchlow in his book, Islamic Patterns: An Analytical and Cosmological Approach.  This explains how ornamented objects as varied in size as a book or a mosque, were treated by artists using the same geometric methods adopted to the size and nature of the object being ornamented.
On the other hand Owen Jones, in The Grammar of Ornament, describes a different construction method whereby this type of interlace ornament is, instead, designed based on a foundation of geometric grids; with the same foundational grids re-drawn to the size of the object.
