The two main devices (symbols) in the Croft blazon are the lion passant and lozengy. The three main tinctures (colors) are gules, erminois and or .
The bold red colour on a heraldic shield is known as gules. It has a long history within heraldry, it is known that one of those who besieged the scottish castle of Carlaverock in 1300 was the French knight Euremions de la Brette who had as his arms a simple red shield.1. The word gules is thought to come from the Arabic gule, or “red rose” 2. Later writers associated it with the precious stone ruby and the metal iron 3, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
Ermine and its variants is a very ancient pattern. It has a long association with royalty and the nobility in general and hence represents “Dignity” wherever it is found 4. The ermine pattern is white with, typically, a three dots and a dart grouping representing the tail of the furred creature.5. Erminois is a variant in which the field is or (gold) and the ermine tails sable (black).
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” 6. 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 7. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 8.
There can be no animal more clearly associated with Heraldry than the lion, majestic King of the Beasts. Originally it appeared only in one pose, erect, on one paw, with the others raised 9 but such was the popularity of this figure, and the need to distinguish arms from each other, that it soon came to be shown in an enormous range of forms 10. The lion passant is an example of these modified form, showing the creature on all fours, as if walking proudly. In common with all reprensentations of the lion it can be taken to be an “emblem of deathless courage”. 11
Anyone who has seen a typical Jester’s or Harlequin’s outfit has seen the treatment known as lozengy – a pattern of interlocking diamonds of two different colours 12. It normally covers the whole field of the shield, as in the ancient arms of FITZ-WILLIAM, Lozengy, argent and gules, a striking example of the form.
