The four main devices (symbols) in the Steven blazon are the hand, crescent, mullet and chevron. 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 hand, unless we are told otherwise is a dexter (right) hand shown palm outwards and fingers upwards.6A Glossary of Terms used in Heraldry, J.B. Parker, 1894 P305. It demonstrates faith, sincerity and justice, and in the form of two right hands clasped can mean union or alliance7The Symbolisms of Heraldry, W Cecil Wade 1898 P92. There is a special form called the “Hand of Ulster” which is a sinister hand gules on an argent background (a left hand, red upon white). Originally the Badge of Ulster, the Province of Northern Ireland, it has come to be used as an addition to existing arms, in an escutcheon (small shield) or canton (small square) to indicate that the holder is also a Baronet.8Heraldry Historical and Popular, Charles Boutell, 1864 P56
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, P146xz`, and the crescent Is a typical example of this, and can appear in any of the main heraldic tinctures. Some common is this device that there are special names for its appearance in various orientations – whilst it lies normally with points upward, the decrescent points to the sinister side, and the increscent to the dexter 10A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Moon. The allusion, obviously is to the shape of the moon in the sky (indeed, the French have a version “figuré” which includes a face!) and has been said to signify both “honour by the sovereign” and “hope of greater glory” 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P106.
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” 12Boutell’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 13A 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” 14The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P105.
