Designs such as this one could well have been done by the ancient Celts. Their art was characterized by its abstract nature, balance of form, delicacy, and most of all by its spirals and interlacings. The interlaced knot work patterns with their unbroken lines, symbolize eternity and the process of man's constant spiritual growth. This pin is made of wheat straw. Approx. size: 2 1/4" x 2 1/4"
