A breastplate is a protective garment that covers the torso, historically employed in armor, religious iconography, or as a symbol of status. From the steel plates worn by medieval knights to the gem-encrusted breastpiece of the biblical high priest, its role and significance have transformed over time.
Authors such as Max Brand emphasized its physical weight in military settings, while Edward Lewes Cutts described its medieval construction. Robert Macalister associated it with sacred attire, and B.G. Jefferis examined its medical relevance. Contemporary bulletproof vests reflect its enduring protective function, yet its symbolism—whether divine, martial, or decorative—continues to be deeply rooted in cultural and historical contexts.
