The two main devices (symbols) in the Butter blazon are the heart and cross. The three main tinctures (colors) are sable, argent and gules .
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.
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.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”6The 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 7Understanding 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).8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
The heart is represented by the conventional symbol that we see today on playing cards. In later arms it can also appear emflamed and crowned. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Heart Guillim, the 17th century heraldic author, believes that it shows the holder to be a “man of sincerity…who speaks truth from his heart”. 10A Display of Heraldry, J. Guillim, Blome, London, 1679, P184
No other symbol appearing in heraldry is subject to as much variation as the cross 11Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 47. Mediaeval Europe was a deeply religious and Christian and many of the nobility wanted to show their devotion by adopting the symbol of the cross as part of the arms. In its basic form, the cross is created from two broad bands of colour at right angles covering the whole extent of the shield. It has been subject to all manner of embellishment, and the interested reader is referred to the references, especially Parker’s Heraldic dictionary for many examples of these. 12A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Cross 13A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P106 14A Treatise on Heraldry, J. Woodward, W & A.K Johnston, Edinburgh & London, 1896, P160-173 Suffice it to say that any armiger would be proud to have such an important device as part of their arms.
