The main device (symbol) in the Harewell blazon is the lion. The two main tinctures (colors) are sable and argent.
Sable, the deep black so often found in Heraldry is believed to named from an animal of the marten family know in the middle ages as a Sabellinœ and noted for its very black fur 1. In engravings, when colors cannot be shown it is represented as closely spaced horizontal and vertical lines, and appropriately is thus the darkest form of hatching, as this method is known 2. Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 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.
The art of heraldry would be significantly poorer if we were without the lion in all its forms. Most general works on Heraldry devote at least one chapter solely to this magnificent creature and its multifarious depictions 6 7 8. Some of the earliest known examples of heraldry, dating right back to the knighting of Geoffrey of Anjou in 1127, where he is shown with six such beasts upon his shield 9 .The great authority on heraldic symbology, Wade, points out the high place that the lion holds in heraldry, “as the emblem of deathless courage” 10, a sentiment echoed equally today.
