The main device (symbol) in the Denhoff blazon is the boar. 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 1A Glossary of Terms used in British Heraldry, J.H.

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 2Boutell’s Heraldry, J.P.

Although it may seem a sombre tone, and does indeed sometimes denote grief, it is more commonly said to represent Constancy 3The Symbolisms of Heraldry, W.

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) 4Understanding Signs & Symbols – Heraldry, S. Oliver & G. Croton, Quantum, London, 2013, P53. In a sketch or drawing it is represented by plain, unmarked paper 5A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1847, P11.
In the middle ages, the wild boar, a far more fearsome creature than its domesticated relative, the pig was a much more commonly seen animal than today. It was also known as a sanglier. 6Boutell’s Heraldry, J.P. Brooke-Little, Warne, (revised Edition) London 1970, P 72 It can appear in many of the same poses that we see for the lion, but has its own (easily imagined!) position known as enraged! 7A Glossary of Terms used in British Heraldry, J.H. Parker, Oxford, 1894, Entry:Boar We should not be surprised then that this “fierce combatant” is said to be associated with the warrior. 8The Symbolisms of Heraldry, W.
