The main device (symbol) in the Hodyc blazon is the proboscis. The two main tinctures (colors) are argent and gules.
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) 1. In a sketch or drawing it is represented by plain, unmarked paper 2.
The bold red colour on a heraldic shield is known as gules. It has a long history within heraldry, it is known that one of those who besieged the scottish castle of Carlaverock in 1300 was the French knight Euremions de la Brette who had as his arms a simple red shield.3. The word gules is thought to come from the Arabic gule, or “red rose” 4. Later writers associated it with the precious stone ruby and the metal iron 5, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
A term probably unfamiliar to many readers, proboscis is a term often found in the heraldry of continental Europe and represents the trunk of an elephant. They are exclusively found in pairs, and only in the crest above the shield in a full achievement of arms. The mouth may be a different colour, and in some cases may hold objects such as ostrich feathers. Little is actually known about their origin or meaning, an interesting mystery for future heraldic scholars to address.
