Glass: A World History

Imagine a world without glass: no light bulbs, no windshields, no telescopes, no computer screens, and, of course, no glasses. "It is true that other substances, such as wood, bamboo, stone, and clay, can provide shelter and storage," write Alan MacFarlane and Gerry Martin in Glass: A World History. "What is special about glass is that it combines these and many other practical uses with the ability to extend the most potent of our senses, sight, and the most formidable of human organs, the brain." As a piece of technology, however, glass has received almost no previous attention. Nobody knows who invented it, though the ancient Egyptians or Mesopotamians are the likeliest candidates. It wasn't until Europe's early Renaissance, however, that glass was used for something more than mere jewelry and ceramics. It played a vital role in the growth of Western science, marking a key difference between European civilization and civilization everywhere else. "The invention of spectacles [in the 13th century] increased the intellectual life of professional workers by fifteen years or more," say the authors--a development of enormous economic and cultural importance that contributed to "the foundations for European domination over the whole world during the next centuries." This is a bold and beguiling thesis, and it's a wonder that it took until now for somebody to think of it and articulate it so well. --John J. Miller
