The two main devices (symbols) in the Wirthmann blazon are the wing and eagle. 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.
Wings are frequently observed in coats of arms. Unless otherwise specified they should be shown as eagle’s wings, with a realistic appearance. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Wing They can appear singly or in pairs, in which form they are very often found in the crest, which rests above the shield in a full achievement of arms. Wade, quoting Quillim, suggests that the use of the wing on the shield signifies “celerity and protection or covering”. 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P73
Where the lion is undisputed king of the animals, the eagle undoubtedly plays the same role in the realm of the birds, its use in this form dating back to at least the Roman period 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Eagle. They tend to be illustrated in quite some detail, especially in continental European arms, and have almost as wide variety of postures and accessories as the lion, well illustrated in the reference 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P235-238 as well as being just the eagle’s head or eagle’s leg. The symbology of the eagle is deep and complex, Wade devotes several pages to the subject 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P72-74, but suffice it say that it has long been associated with Empire and those held in high honour – any armiger would be pleased to have any form of Eagle upon their arms!
