The Celtic Trinity Knot, also known as the Triquetra, is a symbol of three interconnected loops or arcs that form a triangular shape. It is a prominent symbol in Celtic culture and art, particularly in Irish and Scottish traditions. The Trinity Knot is often associated with the concept of three in one, representing the Holy Trinity (Father, Son, and Holy Spirit) in Christian contexts, or the interconnectedness of elements and cycles in pagan traditions.
