The four main devices (symbols) in the Loat blazon are the wings, chief, bendy and wings. The three main tinctures (colors) are vert, argent and ermine .
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Vert. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
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.
Ermine is a very ancient pattern, and distinctive to observe. It was borne alone by John de Monfort, the Earl of Richmond and Duke of Brittany in the late 14th century 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P69 It has a long association with royalty and the nobility in general and hence represents “Dignity” wherever it is found 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P39. The ermine pattern is white with, typically, a three dots and a dart grouping representing the tail of the furred creature.8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 28. The ermine spot is sometimes found alone as a special charge on the shield.
Wings are frequently observed in coats of arms. Unless otherwise specified they should be shown as eagle’s wings, with a realistic appearance. 9A 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”. 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P73
The chief is an area across the top of the field 11Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 40. It appears in many different forms and can itself be charged with other charges and ordinaries, 12A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Chief, being treated almost as if it were a completely separate area. In its simplest form it can be clearly identified. Early examples include the award by Henry III of England to the knight Robert de MORTEYN BRETON of Ermine, a chief gules.
Knowing that the bend is a diagonal stripe of colour, we can easily conclude that bendy is the variant whereby the whole of the shield is covered with diagonal stripes of alternating colours, usually around 4 or 5 of each colour. 13A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bend We should not assign any particular significance to the choice of this pattern, but rather more to the colours they are composed of.
