The two main devices (symbols) in the Alopeus blazon are the bend and key. The two main tinctures (colors) are azure and or.
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.
The bend is a distinctive part of the shield, frequently occuring and clearly visible from a distance – it is a broad band running from top left to bottom right 6. Indeed, so important is the bend that it was the subject of one of the earliest cases before the English Court of Chivalry; the famous case of 1390, Scrope vs Grosvenor had to decide which family were the rightful owners of Azure, a bend or (A blue shield, with yellow bend). 7. The bend is held in high honour and may signify “defence or protection” and often borne by those of high military rank 8.
Although we expect to find fierce creatures and fearsome weapons depicted in a coat of arms this is not always the case – sometimes simple household objects are used 9. The key is a typical example of this. Sometimes these objects were chosen for the familiarity they would have for the obsever, helping them identify the owner, and sometimes they were used because of some association with the owner, or a similarity to the family name. 10 In other cases, Wade suggests that their appearance can be taken to indicate “guardianship and dominion”. 111
