This pattern is found carved in stone at Meigle in Perthshire, Scotland. It is created from one continuous line, which represents eternity, fidelity, and unity to a thought, person or idea. The inner pattern consists of four triquetras, each triquetra represents one of the four seasons. A triquetra represents the three forces of nature: earth, air and water. The symbol was later used by the Christians to symbolize the holy Trinity which made it easier to integrate Christian and pagan beliefs. The circle which encompasses the pattern symbolizes the sun, also worshiped by the druids.
