Celtic Cross Pendant on 18 inch chain in sterling silver. Legend: The subtle merging of cultures characterising the ancient Celtic church is brilliantly represented in the Celtic Cross. Here the Sun Wheel, symbol of the eternal cycle of life, is joined with the Christian Cross symbol of the risen Christ. It is believed that St. Patrick combined these to show pagan followers the importance of the cross. These exquisitely carved monuments can still be seen in Irish monastic sites.
