Lightbulb Moments in Human History: From Priests to Polymaths

Big Ideas. Bizarre Beliefs. Blunders & Breakthroughs.

From medieval monks to Renaissance rebels, humanity kept the flame of knowledge alive-sometimes by candlelight, sometimes by bonfire.

In this smart, irreverent, and unexpectedly optimistic sequel to

From Cave to Colosseum, Scott Edwin Williams charts our uneven crawl out of the so-called Dark Ages. Meet the polymaths, philosophers, poets, plague victims, and pious priests who collectively rebooted civilization.

LIGHT THE CANDLE. ILLUMINATE THE WORLD.
