The two main devices (symbols) in the Hepell blazon are the inescutcheon and border. The two main tinctures (colors) are ermine and gules.
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 1A 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 2The 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.3Boutell’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.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”4The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 5Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P77.
The escutcheon simply represents smaller shield shapes included within the shield, and its close relative, the inescutcheon is just a larger version occupying most of the field. 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Escutcheon There is no particular significance that can accorded to the escutcheon itself, but attention should be paid to the colour and devices that are borne upon it. The escutcheon may also be added to an existing coat of arms either as recognition of some additional honour (an escutcheon of augmentation”) or in the case where arms that are already quartered are to be combined an escutcheon with the new arms may be placed overall (an ”escutcheon of pretence”). 8Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 126 & 141
The border, (sometimes bordure) is a band running around the edge of the shield, following the edge contours and being differently coloured, possibly holding a series of small charges placed on top of it 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bordure. According to Wade, the bordure itself has no direct meaning, but is perhaps a container for the meaning of its colour or those additional charges placed upon it 10The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P50
