The four main devices (symbols) in the Lambert blazon are the lamb, tree, cinquefoil and lion rampant. The two main tinctures (colors) are vert and gules.
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!
Red in heraldry is given the name Gules, sometimes said to be the “martyr’s colour”4. The colour is also associated with Mars, the red planet, and the zodiacal sign Aries 5. Later heralds of a more poetical nature would sometimes refer to the colour as ruby, after the precious stone.6.
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. 7 Its significance is obviously religious in nature, “befitting one a brave, resolute spirit”, according to Guillim. 8
Amongst the natural objects depicted on a coat of arms, trees feature frequently, either in whole or as individual branches and leaves. 9. Sometimes the species or the part of tree was chosen as an allusion to the name of the bearer, as in Argent three tree stumps (also known as stocks) sable” for Blackstock 10 Trees of course had long been venerated and its use in a coat of arms may have represented some association with the god Thor 11
Natural objects abound in heraldry, and one category that gives especial delight are the many flowers and flowering plants that frequently occur 12. The cinquefoil is also of this type, being drawn, at least a little, realistically and often to very pleasing effect. It is shown as five-petalled flower, each petal quite rounded but with a distinct tip. It is sometimes pierced with a hole in the centre and usually appears on its own, without any leaves. 13 It has no fixed colour but can appear in any of the available heraldic tinctures.
