The main device (symbol) in the Millman blazon is the gauntlet. The two main tinctures (colors) are azure and argent.
Azure is the heraldic colour blue, usually quite a deep, dark shade of the colour (there is a lighter blue that sometimes occurs, known as celestial azure). If colour printing is not available then it can be represented by closely spaced horizontal lines in a scheme known as “hatching” 1Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 26. The word is thought to originate from the Arabic lazura and it represents the colour of the eastern sky.

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) 3Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 4A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
The gauntlet is an armoured glove, part of a knights attire and when used as a device on the shield it should be stated which hand it is for. 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Gauntlet They are quite a complex device visually, with distinct panels and rivets visible. Wade tells us, probably with good reason that it represents “a man armed for performance of a martial enterprise”. 6The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P93
