The two main devices (symbols) in the Capper blazon are the cap and rose. 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 cap, also known as infula/infuld appears in many forms, as charges on the shield, as part of the costume of various characters and in the crest. To determine the exact pattern of headwear more detail is normally given. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:cap
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P262. The rose is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It has long been present in English heraldry, and as a badge and symbol played an enormous in English history throughout the conflict between rival dynasties known as the War of the Roses. In addition to these familial uses, Wade suggests that red roses signify “beauty and grace” and the white represents “love and faith”. 11The Symbolisms of Heraldry, W.
