The knots symbolize eternity, unity, and the interconnectedness of life. These decorative motifs can be found in various forms of art, including manuscripts, jewelry, and architecture. Celtic knots are characterized by their looping shapes and can vary in complexity, from simple designs to elaborate patterns. They continue to be popular in modern art and design, reflecting a rich cultural heritage.
