The bold red colour on a heraldic shield is known as gules. It has a long history within heraldry, it is known that one of those who besieged the scottish castle of Carlaverock in 1300 was the French knight Euremions de la Brette who had as his arms a simple red shield.1The Siege of Carlaverock, N.

It shares many of the poses to be found with the lion, but also one almost unique to the deer, grazing, as if the animal is still unaware of the hunter’s approach. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Deer. In common with all symbols related to the hunt we probably need look further for their intended meaning than the pleasure taken by the holder in such pursuits! 8The Symbolisms of Heraldry, W.
