The two main devices (symbols) in the Ackworth blazon are the coronet and griffin. The two main tinctures (colors) are gules and argent.
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.
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) 4. In a sketch or drawing it is represented by plain, unmarked paper 5.
Crowns are frequently observed in Heraldry 6, but we should not make the mistake of assuming that these are always on Royal arms 7. Many of the orders of nobility across Europe were entitled to wear crowns and coronets, Dukes, Earls, Viscounts and Barons in England each had their own distinctive headwear 8. The coronet is an example of this. It may also be the case that a crown is added to an existing coat of arms as an augmentation in recognition of some service to a King 9.
In the mediaeval period there was no real percieved difference between real and mythical animals, after all, much of the world remained unknown and who was to say what strange and magical creatures existed in distant lands? As heraldry developed a whole menagerie of imagined creatures 10 came into being, and their various representations became more or less standardised in form and appearance. The griffin is perhaps the most common of these creatures, being a chimera with the body of a lion and the head and wings of an eagle. 11. It is most often in the pose known as rampant segreant, on its hind legs with claws and wings extended. Vinycomb has much to say on the subject of the griffin, perhaps summarised in his belief that it represents “strength and vigilance”.]12
