The two main devices (symbols) in the Husband blazon are the mullet and martlet. The two main tinctures (colors) are gules and argent.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.3A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P77.
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.
The heraldic mullet, not to be confused with the fish of that name, is shown as a regular, five pointed star. This was originally, not an astronomical object, but represented the spur on a horseman’s boot, especially when peirced, with a small circular hole in the centre it represents a type of spur known as a “rowel” 6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 97. A clear example can be found in the arms of Harpendene, argent, a mullet pierced gules. The ancient writer Guillim associated such spurs in gold as belonging to the Knight, and the silver to their esquires 7A Display of Heraldry, J. Guillim, Blome, London, 1679, P107. In later years, Wade linked this five pointed star with the true celestial object, the estoile and termed it a “falling star”, symbolising a “divine quality bestowed from above” 8The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P105.
The martlett is by far the most common bird to appear in British Heraldry, perhaps only equalled by the eagle, however it is not a species ever to be found in an ornithologists handbook! The word itself is though to have come from the French word merlette, the female blackbird and itself a similar type of charge used in French Heraldry. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Martlet. Over time the image has become quite stylised, without visible legs or distinctive feathers. Wade suggests that this representation arises from “the appearance of the bird of paradise to ancient travellers” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P79. Other bird species may be named in coats of arms (cornish chough is a frequent example) but in actual execution their appearance is often indistinguishable from the martlet.
