The three main devices (symbols) in the Hagan blazon are the sea lion, anchor and waves. The three main tinctures (colors) are gules, argent and azure .
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.1. The word gules is thought to come from the Arabic gule, or “red rose” 2. Later writers associated it with the precious stone ruby and the metal iron 3, perhaps because of the red glow of iron in the heat of the blacksmith’s forge.
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.
Azure is the heraldic colour blue, usually quite a deep, dark shade of the colour (there is a lighter blue that sometimes occurs, known as celestial azure). If colour printing is not available then it can be represented by closely spaced horizontal lines in a scheme known as “hatching” 6. The word is thought to originate from the Arabic lazura and it represents the colour of the eastern sky. It is also said to be the colour associated by the Catholic Church with the Virgin Mary and hence of particular significance 7.
The sea lion is not the large aquatic creature that we are familiar with today, but a regular heraldic lion with a fish’s tail. 8 (In fact many new mythical creatures were created by heralds by prefixing them with the word “sea” and adding a fishtail!). Its meaning can be taken to be the same as the land-based king of the beasts.
A wide variety of inanimate objects 9 appear in coats of arms, so of them still recognisable today, others now rather obscure. The images used are often simplified and stylised, the anchor is a typical case. For any meaning, we need look no further than a nautical or sea-faring heritage. Indeed, some arms go into great detail of the colours and arrangement of the stock, stem, cables and flutes of the anchor reflecting a detailed knowledge of the form and use of this device. 10.
The decorative edge pattern Wavy, sometimes written as undy is, for obvious reasons, associated with both water and the sea 11. Indeed, a roundel with alternating bars of azure and argent (blue and white) is known by the shorthand term fountain, representing water at the bottom of a well 12.
