The main device (symbol) in the Jerlicz blazon is the fox. 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.
The fox occurs frequently in arms, possibly a reference to the enjoyment of the hunt. It certainly holds no negative connotations but should be seen as a creature of great “wit and facility of device” (“as cunning as a fox”). 6 It can appear at first glance quite similar to the wolf but should be smaller, with a bushier tail, kept low to the ground. 7
