The four main devices (symbols) in the Potter blazon are the chevron, cinquefoil, wing and fleshpot. The three main tinctures (colors) are azure, argent and gules .
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 1A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Azure. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 2The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36.
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) 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 4A 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”5The 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 6Understanding 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).7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
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 8A Display of Heraldry, J. Guillim, Blome, London, 1679, (various), or additional cross-pieces used to strengthen the shield and painted a different colour.9The 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” 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P45, possibly becuase of its resemblance to the roof truss of a house.
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 11A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P262. The cinquefoil is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It is shown as five-petalled flower, each petal quite rounded but with a distinct tip. It is sometimes pierced with a hole in the centre and usually appears on its own, without any leaves. 12A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Cinquefoil It has no fixed colour but can appear in any of the available heraldic tinctures.
Wings are frequently observed in coats of arms. Unless otherwise specified they should be shown as eagle’s wings, with a realistic appearance. 13A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Wing They can appear singly or in pairs, in which form they are very often found in the crest, which rests above the shield in a full achievement of arms. Wade, quoting Quillim, suggests that the use of the wing on the shield signifies “celerity and protection or covering”. 14The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P73
