Final answer:
A blazon is a poetical or heraldic description or representation of a coat of arms. They have fallen out of favor due to the decline in the use of heraldry and the rise of graphic design and modern branding techniques. Blazons are primarily studied and used by historians, genealogists, and those interested in heraldry as a form of historical and cultural identification.
Step-by-step explanation:
A blazon is a poetical or heraldic description or representation of a coat of arms. It was used in medieval Europe as a way to describe and identify different coats of arms. However, blazons have fallen out of favor in modern times due to the decline in the use of heraldry and the rise of graphic design and modern branding techniques.
For example, in the Middle Ages, a blazon might describe a coat of arms using symbols, colors, and patterns, such as 'argent, a lion rampant gules.' This would indicate a silver shield with a red lion standing upright. This description would allow individuals to visually identify different coats of arms. However, as heraldry fell out of use and coats of arms became less common, blazons lost their significance and practicality.
Today, blazons are primarily studied and used by historians, genealogists, and those interested in heraldry as a form of historical and cultural identification.
