The two main devices (symbols) in the Brogg blazon are the barrulet and tower. The three main tinctures (colors) are sable, or 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 1. 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 2. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 3.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.4. Along with, argent, or silver it forms the two “metals” of heraldry – one of the guidelines of heraldic design is that silver objects should not be placed upon gold fields and vice versa 5. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.6.
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) 7. In a sketch or drawing it is represented by plain, unmarked paper 8.
The barrulet is the very narrowest member of the family of horizontal bands across the shield. The largest is the fesse, originally occupying one third of the height of the shield, barrulets are a mere one twentieth of the height and always occur in groups 9. Like the other bar-like objects, Wade associates the use of this device with those who “set the bar…against angry passions and evil temptations” 10.
Architectural items, from individual components to entire buildings 11 feature frequently as charges In a coat of arms. Not surprisingly, considering the times from which many arms date, fortifications are common. The tower Is a typical example of an object from the world of architecture adopted, albeit in a stylised form, for use in heraldry. It can be placed alone, or frequently with three turrets on the top, known as a tower triple towered, and can have doors and windows of a different colour. 12 In continental European heraldry they are often accompanied by pictorial effects such as armoured knights scaling them on ladders.
