The three main devices (symbols) in the Muskett blazon are the lion’s head, bar and antelope. The two main tinctures (colors) are argent and gules.
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.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”3The 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 4Understanding 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).5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P154
There can be no animal more clearly associated with Heraldry than the lion, majestic King of the Beasts.6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 64 The head of the lion also appears alone on many coats of arms, but its use in this form is largely to enable a clear difference from similar arms that use the complete animal, and its significance should be taken to be the same as the lion entire, being a symbol of “deathless courage”. 7The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P59
The bar is a thin, horizontal stripe across the centre of the shield 8A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Bar, usually in groups of two or three (any more and there would be confusion with barry, a treatment of horizontal lines of alternating colours). Bars can be a distinctive and easily recognised device, early examples include those awarded by Henry III of England to the family MAUDYT Argent, two bars gules.
The ibex or antelope was drawn by heraldic artists in rather more fearsome aspect than its real-life appearance, with large horns, mane and a long tail. 9A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Antelope These days we regard the ibex as being a member of the goat family rather than an antelope, but in the middle ages there were was no real distinction between these animals. They could adopt many of the poses of the lion, such as rampant and statant. 10A Complete Guide to Heraldry, A.C. Fox-Davies, Bonanza (re-print of 1909 Edition), New York, 1978, P210
