The two main devices (symbols) in the Mainard blazon are the hand and chevron. The two main tinctures (colors) are gules and argent.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P52. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).3A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
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
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 9A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.10The Pursuivant of Arms, J. R. Planche, Hardwicke, London 1859. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 11The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
