The Story of Mankind is a massive carved limestone screen divided into fifteen small rectangular spaces that Lawrie termed “hieroglyphs”. It was created to symbolize the purpose of the International Building and to chronicle mankind’s progress, starting with the bottom center’s four figures depicting the races of mankind. The sailing ship image above them symbolizes international trade, while other symbols include a Norman tower as pre-industry, a lion as kingdoms of the world, and Mercury as worldwide communication. The clock and rays at the very top represent earth.
