This coaster is a really unique addition to your home decor. It is made with stained mirror using the colours and patterns that are found in Celtic artwork, including the famous Book of Kells. The corners are decorated with elegant Trinity Knots; the simplest of Celtic Knots symbolising a triune God. For the Celts everything came in threes, maid, mother, crone and the three elements earth, fire and water. Christianity embraced this knot to symbolise the Father, Son and Holy Spirit. This use of this trinity knot in art is associated with eternity and eternal love. In the centre there is a beautiful green harp. This instrument is Ireland's official cultural and political symbol and appears in Celtic artwork, public notices and our currency. A beautiful gift from Ireland.
