Celtic Knotwork is characterized by the "endless knot" with no beginning or end, and represents eternity in all its glory. Incorporated into Celtic art for millennia, the Celtic Knot has become distinctly recognizable for its interconnectedness and appears in myriad forms and designs, each one more compelling than the last.
