The main device (symbol) in the Achelton blazon is the falcon. 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.
Birds of great variety occur throughout heraldry, at least in name 6. The falcon is a bird long associated with hunting and we need look no further than a liking for this pursuit for its presence on many early coats of arms. 7 We also find many of the accessories used in falconry depicted on arms, and a surprising number of terms from the art of falconry have found use in modern English idioms and the interested reader is recommended to search out the origins of the phrases hoodwinked and “cadging” a lift.
