The Ancients also believed the Cat Sidhe is a guardian and a symbol of change, flexibility and adaptability. Often when a cat makes an uncommon appearance in our lives it is a message for us to make some fresh changes in our lives, as well as be more flexible in our thinking.
All Celtic knots, whether square, triangle or round, symbolize“no beginning, no end... infinity,” the intertwining of this world and the “other” or spiritual world, the continuity of life paths, the mingling of relationships, and the binding together of all.
The history of the Celts is an oral one and the exact meaning of their artwork, including all Celtic knots, is unsure. However scholars believe the round Lugh knot comes from Celtic mythology with Lugh being the Celtic god of Harvest; to this day a festival called Lughnasa is celebrated, in Ireland and in the Celtic Isles, halfway between the Summer solstice and Autumn equinox.
The triangular three-point knot called Triquetra, Triknot or Trinity has meaning for Christians and pagans alike. Early Christians adopted it as a symbol of the three-in-one God or Trinity - Father, Son, and Holy Spirit. The Triquetra is often found in insular art such as illuminated manuscripts such as the Book of Kells. It is also found in similar artwork on Celtic crosses from the early Christian period. Pagans took it as a symbol of division of the world into the realms of Earth, Sea and Sky, and as a symbol of the triple goddesses, for example, Epona and The Morrígan.
