The main device (symbol) in the Duly blazon is the chevron engrailed. 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 chevron is one the major shapes used upon a shield, known as ordinaries, being in the form of an inverted ‘v’ shape 6. It is a popular feature, visually very striking and hence developed to have various decorative edges applied to distinguish otherwise identical coats of arms. The edge pattern engrailed is a series of scalloped indentations with the points facing outwards – and should not be confused with invected, which has the points facing inwards! Wade believes that both of these indented forms represent “earth or land”, and one perhaps can indeed see the furrowed earth embodied in them.
