Spirals on ancient tombs go back 5,000 years. Barclodiad y Gawres in Anglesey is an ancient tomb that dates from the Neolithic era. There are spirals on the stones inside the tomb’s passage and chambers. They were very carefully carved, especially when you think that the people who made them had no iron tools. No one today knows what the spirals meant to people thousands of years ago. Perhaps they were just decorations, or perhaps they stood for life or eternity.
