Trinity knot Celtic design bangle in polished sterling silver. Expanding style for ease of wear and fit. The beautiful simplicity of the trinity knot symbolises eternity and continuity. The interlace pattern never ends and is the key to Celtic knot work. To the Celts the Trinity Knot is believed to have meant many things; mind, body, spirit; earth, sea and sky and beginning, middle and end – continuity. The symbol decorates our illuminated manuscripts such as The Book of Kells and is found on Celtic crosses and Celtic stones all around the country. The Trinity Knot has been adopted from ancient Celtic art by Christianity as a symbol of the Holy Trinity; Father, Son & Holy Spirit. The Trinity Knot is the most well known and loved of all Celtic knots and in modern times has been given as a token of promise; to love, to honour and to protect.
