Less than 50,000 years ago mankind had no art, no religion, no sophisticated symbolism, no innovative thinking. Then, in a dramatic and electrifying change, described by scientists as "the greatest riddle in human history," all the skills and qualities that we value most highly in ourselves appeared already fully formed, as though bestowed on us by hidden powers.

Published to great acclaim in 1873, Walter Pater’s compendium of idiosyncratic, impressionistic essays on the Renaissance gained him a reputation as a daring modern philosopher. Oscar Wilde called it the “holy writ of beauty.” It was Pater’s cry of “art for art’s sake” that became the manifesto for the aesthetic movement. He believed that art should be sensual and that beauty should rank as the highest ideal. Marked by elegant fluency, Pater’s essays discuss Botticelli, Michelangelo, Leonardo da Vinci, and other artists who, for him, embodied the spirit of the Renaissance.

Like the alphabet, the calendar, or the zodiac, the periodic table of the chemical elements has a permanent place in our imagination. But aside from the handful of common ones (iron, carbon, copper, gold), the elements themselves remain wrapped in mystery. We do not know what most of them look like, how they exist in nature, how they got their names, or of what use they are to us.
