The main device (symbol) in the Ironside blazon is the cross patonce. The three main tinctures (colors) are or, gules and azure .
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P76-77.
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.4The Siege of Carlaverock, N. Harris, Nichols & Son, London, 1828, P180. The word gules is thought to come from the Arabic gule, or “red rose” 5Boutell’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 6Understanding 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.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
No other symbol appearing in heraldry is subject to as much variation as the cross 9Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 47. Mediaeval Europe was a deeply religious and Christian and many of the nobility wanted to show their devotion by adopting the symbol of the cross as part of the arms. Since no two arms could be identical there arose many variants of the cross, typically involving patterning along the edges 10Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P67, or fanciful, decorative endings to the arms of the cross 11A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P128. The cross patonce is typical of these, whereby each arm of the cross expands and ends in a bud-like projection. These cross variations are probably largely for decorative effect, and to differentiate the arms from similar ones and hence their significance is that of the Christian cross itself.
