The two main devices (symbols) in the Brockley blazon are the chief and chequy. The three main tinctures (colors) are argent, or and vert .
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) 1. In a sketch or drawing it is represented by plain, unmarked paper 2.
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 3. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 4. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 5.
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” 6. 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 7. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 8. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
The chief is an area across the top of the field 9. It appears in many different forms and can itself be charged with other charges and ordinaries, 10, being treated almost as if it were a completely separate area. In its simplest form it can be clearly identified. Early examples include the award by Henry III of England to the knight Robert de MORTEYN BRETON of Ermine, a chief gules.
Chequy (a word with a surprising number of different spellings!) is what is known as a treatment, a repeating pattern usually used to fill the whole background of the shield with a series of alternately coloured squares 11. These squares are usually quite small (there should be at least 20 in total), giving the appearance of a chess board, but any combination of colours may be used. It can also be used as a patterning on some of the larger ordinaries, such as the pale and fess, in which case there are three rows of squares. Wade, an authority on heraldic meaning groups chequy with all those heraldic features that are composed of squares and believes that they represent “Constancy”, but also quotes another author Morgan, who says that they can also be associated with “wisdom…verity, probity…and equity”, and offers in evidence the existence of the common English saying that an honest man is a ”Square Dealer” 12.
