The endless knot, symbolising life with its eternal change, was a central symbol in ancient times and is found on many stone monuments,
including the North Cross (8th century, Ahenny/Ireland) and the rune monument from Kirk Michael on Man in the Irish Sea, which was of great importance to the Vikings.

Vikings ca. 800 - 1,100 AD.
