Knot patterns first appeared in the third and fourth centuries AD, and can be seen in Roman floor mosaics of that time.
Interesting developments in the artistic use of interlaced knot patterns are found in Byzantine architecture and book illumination, Coptic art, Celtic art, Islamic art, Medieval Russian book illumination, Ethiopian art, and European architecture and book illumination. (Wikipedia).
A fairy (also faery, faerie, fay, fae; euphemistically wee folk, good folk, people of peace, fair folk, etc.) is a type of mythological being or legendary creature, a form of spirit, often described as metaphysical, supernatural or preternatural.
Fairies resemble various beings of other mythologies, though even folklore that uses the term fairy offers many definitions. Sometimes the term describes any magical creature, including goblins or gnomes: at other times, the term only describes a specific type of more ethereal creature. (Wikipedia).
Celtic knots are a variety of (mostly endless) knots and stylized graphical representations of knots used for decoration, adopted by the ancient Celts.
These knots are most known for their adaptation for use in the ornamentation of Christian monuments and manuscripts like the 8th century St. Teilo Gospels, the Book of Kells and the Lindisfarne Gospels. (Wikipedia).
The love spoon was given to a young woman by her suitor. It was important for the girl's father to see that the young man was capable of providing for the family and woodworking.
Sailors would often carve love spoons during their long journeys, which is why anchors would often be incorporated into the carvings..
