Celtic Knot Charms | Celtic Knot Pendants | Celtic Knot Jewelry -- Celtic Knot Symbolism - Celtic knot symbols date back to around 450 AD and richly characterize Celtic art and tradition. There is a common folklore that each knot has a specific meaning. The problem with this idea is that there are no facts to back it up. There is no 'Rosetta Stone' or reliable 'dictionary' of knots. A general symbolism of Celtic interlace can be expressed as representing the repeated crossings of the Spiritual and Physical Paths in our lives. For many, Celtic Knots represent Eternity -- the Eternity of Life, the Eternity of Nature, and the Eternity of Love, Never-ending.
