The two main devices (symbols) in the Debno blazon are the cross and proboscis. The two main tinctures (colors) are gules and argent.
Gules, the heraldic colour red is very popular, sometimes said to represent “Military Fortitude and Magnanimity”1. It is usually abbreviated as gu and in the days before colour printing was shown in a system known as hatching by vertical lines 2. Although it may look like a French word it is normally pronounced with a hard “g” and may be derived either from the Latin gula (throat) or Arabic gule (rose).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.
No other symbol appearing in heraldry is subject to as much variation as the cross 6. Mediaeval Europe was a deeply religious and Christian and many of the nobility wanted to show their devotion by adopting the symbol of the cross as part of the arms. In its basic form, the cross is created from two broad bands of colour at right angles covering the whole extent of the shield. It has been subject to all manner of embellishment, and the interested reader is referred to the references, especially Parker’s Heraldic dictionary for many examples of these. 7 8 9 Suffice it to say that any armiger would be proud to have such an important device as part of their arms.
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.
