A shield is a piece of personal armor designed to intercept attacks, differing in size, material, and form across cultures and eras. From ancient wooden constructions to medieval heraldic symbols, shields served both practical and symbolic purposes. Sir Thomas Malory depicted them as essential in battle, while Edward B.
Tylor emphasized their evolution from individual protection to collective warfare. Eugène Viollet-le-Duc observed their shift into decorative heraldic emblems, and Arthur Charles Fox-Davies examined their role in marital symbolism. These viewpoints reveal shields as objects of combat, identity, and cultural expression, bridging function and artistry.
