The main device (symbol) in the Acklow blazon is the indented quarterly. The two main tinctures (colors) are azure 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.
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) 3. In a sketch or drawing it is represented by plain, unmarked paper 4.
Quarterly, as its name suggests is a method of dividing the shield into 4, more or less equal parts, conventionally of two alternating colours. 5 To further provide differentiation between arms the lines of the quartering can be given repeating patterns. An example of this is are lines drawn indented, i.e. in a saw-tooth pattern. An early author, Guilllim seeks to associate this decoration with fire 6, and one can see the resemblance to flames. The visual effect is quite striking, an good example being the arms of DUNHAM (Lincolnshire), which are Azure, a chief indented or.
