The four main devices (symbols) in the Dennys blazon are the crescent, chevron, ostrich feather and ducal coronet. The three main tinctures (colors) are azure, or and argent .
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 1. 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” 2.
The bright yellow colour frequently found in coats of arms is known to heralds as Or, or sometimes simply as Gold.3. 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 4. The yellow colour is often associated with the Sun, and the zodiacal sign of Leo.5.
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) 6. In a sketch or drawing it is represented by plain, unmarked paper 7.
For easy recognition of the items on a coat of arms, and hence the quick identification of the owner, bold simple shapes are best. Hence, simple geometric shapes are often used for this purpose 8xz`, and the crescent Is a typical example of this, and can appear in any of the main heraldic tinctures. Some common is this device that there are special names for its appearance in various orientations – whilst it lies normally with points upward, the decrescent points to the sinister side, and the increscent to the dexter 9. The allusion, obviously is to the shape of the moon in the sky (indeed, the French have a version “figuré” which includes a face!) and has been said to signify both “honour by the sovereign” and “hope of greater glory” 10.
The chevron is one the major shapes used upon a shield, known as ordinaries. The inverted ‘V’ of the chevron is perhaps thought to have originated to represent a military scarf folded on the shield 11, or additional cross-pieces used to strengthen the shield and painted a different colour.12. It has also acquired the meaning of “Protection… granted… to one who has achieved some notable enterprise” 13, possibly becuase of its resemblance to the roof truss of a house.
The feather, especially that of the ostrich appears with great regularity in the crests of a full achievement of arms, typically in the shape of a plume. Wade associates this device with “willing obedience and serenity of mind”. 14 They are much less common on the shield itself, unless part of an arrow, which may be feathered of a different colour, or a quill pen. 15
