The two main devices (symbols) in the Materna blazon are the bird and ring. The two main tinctures (colors) are sable and azure.
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 1A 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 2Boutell’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 3The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
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 4A 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” 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
Birds of great variety occur throughout heraldry, at least in name 6A 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 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P164.
The most common form of household jewelery in heraldry is the ring or gem ring, shown with a jewel which may have a different colour. 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:ring Wade, incorrectly terms the annulet a finger ring, but assigns the meaning of “fidelity” to it – more properly this meaning belongs to the gem ring. 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P94
