The three main devices (symbols) in the Ash blazon are the mews, saltire and crescent. The two main tinctures (colors) are gules and azure.
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”1. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 2. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.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 saltire is one the major ordinaries, large charges that occupy the whole of the field 6. Arguably one of the best uses of this device is that of the St. Andrews Cross, a white saltire on a blue background found on the Scottish flag. The saltire is obviously closely related to the Cross, and Wade in his work on Heraldic Symbology suggests additionally that it alludes to “Resolution”, whilst Guillim, an even more ancient writer, somewhat fancifully argues that it is awarded to those who have succesfully scaled the walls of towns! 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.
