Description:
From the dawn of history, long before man could read or write he used symbols and emblems to convey his ideas. In the days of the Roman Empire the Romans carried the eagle atop their standards as a symbol of strength. The Old Celtic clans used a system of colours to indicate social and political standing. The rank of the individual was displayed on his cloak by the number of colours he was permitted.
