The two main devices (symbols) in the Hendley blazon are the hind and mount. The three main tinctures (colors) are vert, azure and argent .
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 1The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P36. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 2A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Vert. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 27. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
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” 4Boutell’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. It is also said to be the colour associated by the Catholic Church with the Virgin Mary and hence of particular significance 5The Symbolisms of Heraldry, W. Cecil Wade, George Redway, London, 1898 P150.
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) 6Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
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 mount (also known as a hillock 10Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 324) is the area at the base of the shield and when so described is almost always green, and somewhere that another charge is placed, to appear more realistic, or give it a specific relationship to other charges around it. 11A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Mount Indeed, unlike like most of the flat, geometric shapes used to divide the field of the shield, the mount may be drawn with tufts of grass and a distinct slope!
