Why this 2000-year-old contract was impossible to falsify

Watch how a traditional marriage document is crafted from copper using a technique that dates back over 2,000 years. The process begins with high-purity red copper sheets, which are heated and carefully hammered over an engraved mold to imprint detailed designs. After shaping, the surface is polished and selectively cleaned to reveal the bright copper patterns. Historically, these copper documents were more than decorative—they played a vital role in legal and social systems, ensuring the rights and agreements between both parties in marriage.
