The two main devices (symbols) in the Cudworth blazon are the demi lion and fesse. The three main tinctures (colors) are erminois, or and azure .
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” 1. 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 2. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 3.
The bright, strong blue color in Heraldry is known in English as azure, and similarly in other European languages – azul in Spanish, azurro in Italian and azur in French. The word has its roots in the Arabic word lazura, also the source of the name of the precious stone lapis lazuli 4. Despite this, those heralds who liked to associate colours with jewels chose instead to describe blue as Sapphire. According to Wade, the use of this colour symbolises “Loyalty and Truth” 5.
The demi-lion is a variant of the typical creature shown only from the waist upward. It can take all same poses and attitudes of its fully represented brethren and often appears to be emerging from some other device such as a fess or chief. 6 No special significance should be given to the demi appearance and it should be taken to have the same meanings and interpretations as the noble king of beasts itself.
The fesse (also found as fess) is one of the major ordinaries to found in heraldry, being a bold, broad, horizontal band across the centre of the shield. It may originally have arisen from the planks of which a wooden shield can be constructed, the centremost plank being painted a different colour 7. It is instantly recognisable as a symbol, for example the arms of COLEVILLE granted during the reign of Hery III are simply or, a fesse gules. With this clear association with the construction of the shield itself, Wade believes that the fesse can be taken to be associated with the military, as a “girdle of honour”.
