This emblem is known as the fret or key pattern. It developed simultaneously throughout the world. In the Native American culture it is used as a seasonal or changing symbol, in eastern thought as a positive directional symbol, in classical Greek culture as a sign of completion, as a border pattern and in Celtic work as a symbol to protect or guard against evil. The pattern represents changes in a person's life. With the arms extending outward it signifies growth and a great source of strength.
