The two main devices (symbols) in the Mort blazon are the lozenge and bend. The two main tinctures (colors) are gules and argent.
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. Harris, Nichols & Son, London, 1828, P180. The word gules is thought to come from the Arabic gule, or “red rose” 2Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 313. Later writers associated it with the precious stone ruby and the metal iron 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
Argent is the heraldic metal Silver and is usually shown as very pure white. It is also known more poetically as pearl, moon (or luna) 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146xz`, and the lozenge Is a typical example of this, and can appear in any of the main heraldic tinctures. It can appear on its own, voided (with the background visible through the middle), and can also be conjoined, whereby adjacent lozenges touch point-to-point. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Lozenge Guillim groups the lozenge with all square shapes as being symbolic of “verity, probity, constancy and equity”. 8A Display of Heraldry, J. Guillim, Blome, London, 1679, P262
The bend is a distinctive part of the shield, frequently occuring and clearly visible from a distance – it is a broad band running from top left to bottom right 9Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 39-40. Indeed, so important is the bend that it was the subject of one of the earliest cases before the English Court of Chivalry; the famous case of 1390, Scrope vs Grosvenor had to decide which family were the rightful owners of Azure, a bend or (A blue shield, with yellow bend). 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P22. The bend is held in high honour and may signify “defence or protection” and often borne by those of high military rank 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P49.
