The main device (symbol) in the Lamott blazon is the bars humettee. The two main tinctures (colors) are sable and argent.
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.
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). Humettee is a word of uncertain origin that means couped or cut. It is applied to so-called ordinaries, the large features that typically extend across the whole of the field, but their description as humettee means that, whilst still occupying the bulk of the space, they are cut short before reaching the edge 6A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Humetty. Thus the bar humettee is one of small number of horizontal bars ending just short of either edge. Richard II of England granted an example of these in the arms of John de DABRICHECOURT, being Ermine, on 3 bars humetty 9 escallops or 3,3,3.
