The two main devices (symbols) in the Loeser blazon are the lamb and eagle. The three main tinctures (colors) are vert, or and argent .
The deep green colour that is so often observed in heraldry is more properly known as vert. According to Wade, the use of this colour signifies “Hope and Joy”, but may also represent, rather delightfully, “Loyalty in Love” 1. It has other names also, the French call it sinople, perhaps after a town in Asia Minor from where the best green die materials could be found 2. More fanciful heralds liked to associate it with the planet venus and the precious stone emerald 3. More strangely, there is some evidence that the term prasin was anciently used, being the Greek for the vegetable we call the Leek!
Or is the heraldic metal Gold, often shown as a bold, bright yellow colour. It is said to show “Generosity and elevation of the mind” 4. Later heralds, of a more poetic nature liked to refer to it as Topaz, after the gemstone, and, for obvious reasons associated it with the Sun 5. In drawings without colour it is usually represented by many small dots, or by the letter ‘O’ 6.
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) 7. In a sketch or drawing it is represented by plain, unmarked paper 8.
The lamb may refer either to the young of the sheep, in which case it is shown entirely in profile, or to the paschal or holy lamb, which turns to face the viewer and has both a halo and a flag on a pole. The flag may be charged with additional items. 9 Its significance is obviously religious in nature, “befitting one a brave, resolute spirit”, according to Guillim. 10
Where the lion is undisputed king of the animals, the eagle undoubtedly plays the same role in the realm of the birds, its use in this form dating back to at least the Roman period 11. They tend to be illustrated in quite some detail, especially in continental European arms, and have almost as wide variety of postures and accessories as the lion, well illustrated in the reference 12 as well as being just the eagle’s head or eagle’s leg. The symbology of the eagle is deep and complex, Wade devotes several pages to the subject 13, but suffice it say that it has long been associated with Empire and those held in high honour – any armiger would be pleased to have any form of Eagle upon their arms!
