The three main devices (symbols) in the Bardwell blazon are the goat, hart and bar gemmel. The two main tinctures (colors) are argent and sable.
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) 1Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
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 3A 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 4Boutell’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 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P35.
In the mediaeval period there was no real percieved difference between real and mythical animals, after all, much of the world remained unknown and who was to say what strange and magical creatures existed in distant lands? Nevertheless, real animals 6A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P191 are perhaps one of the most common sights on coats of arms, especially animals of European origin. The goat Is a typical example of these. Guillim, writing in the 17th century suggested that it may represent a “martial man who wins victory by…policy [rather] than valour”, a diplomat by any other name. 7A Display of Heraldry, J. Guillim, Blome, London, 1679, P119
Many different forms of the deer, hart, roe-buck and other appear in rolls of arms, though often of similar appearance. The precise choice of animal possibly being a reference to the family name. 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Deer If there is any symbology intended it is probably that of enjoyment of the hunt, deer in all its form being a popular prey. 9The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P30
The bar is a thin, horizontal stripe across the centre of the shield, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). It is also possible to place decorative edges along bars, typically these are smaller than those found on the major ordinaries like the fess and pale, but have the same design and share the same meanings. Gemel simply means “doubled” 10A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Gemel, so whatever it is applied to appears twice, slightly reduced in size to occupy a similar amount of space to the original. This is different from having “two” of something, and indeed it is possible to have, for example two bars gemel, in which there are two, clearly separated pairs of bars.
