The label on back of tile reads... 

The true meaning behind Celtic  designs is lost in the mists of  history, little real documentary evidence exists today. Whatever the  thoughts in the minds of those artists long ago we encourage you to enjoy their beauty and dream your own thoughts.
The four  elements of the design are often associated with the four seasons, Spring, Summer, Autumn and Winter; the compass points, North, South, East and West and the four elements Earth,  Air, Fire and Water.The four sided pattern is also called the shield knot symbolizing protection.

We make our tiles from stoneware clay, they are individually hand crafted and are twice fired in our kilns. The Square tiles are mounted on a 5 1/2 inches square black wood frame. A wall hanging clip, rubber wall protectors and a descriptive label (see individual tile picture for details) is attached to the back of the frame.

All tiles are individually gift boxed with a bubble wrap liner.
