Horse brasses are decorative brass ornaments, typically attached to leather straps on a horse's harness. They were particularly popular in Britain from the mid-19th century through the mid-20th century, often used for parades, festivals, and special occasions. These ornaments served both as decoration and as a form of good luck charm, with many designs carrying symbolic meanings.

This particular medallion, with its shield and crescent motifs, likely served as a decorative element on a horse's martingale or bridle. The intricate cut-out pattern and the material suggest it was crafted by skilled artisans. While many horse brasses were mass-produced, unique designs and those in good condition can be sought after by collectors. 941
