The two main devices (symbols) in the Raven blazon are the raven and torteaux. The two main tinctures (colors) are or and sable.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.1Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 2A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P85. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Sable. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 5Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 6The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
Birds of great variety occur throughout heraldry, at least in name 7A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P233. In truth, despite the proliferation of species, the actual depictions can sometimes be hard to distinguish! The crane, heron and stork are commonly to be found on a coat of arms but all tend to share the same stylised appearance 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P164. The raven is amongst the mjaor bird species to appear in heraldry.
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 9A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P146 One of the simplest such shapes is the plain circle, known to heralds as the roundle. 10A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Roundle So popular is this charge that a shorthand has arisen for roundles of a particular colour and torteau is a roundle gules, or red. (We must be careful however not to confuse this with the word in French heraldry, in which torteau means roundle and must have the colour specified.) Most authorities agree that the English usage signifies the “Manchet cake” or communion wafer and thus is a symbol of religious allegiance.
